Crystal structure of bis-(ammonium) bis-[penta-aqua-(di-methyl-formamide)-zinc(II)] deca-vanadate tetra-hydrate.

ABSTRACT: The crystalline product (NH₄)₂[Zn(C₃H₇NO)(H₂O)₅]₂[V₁₀O₂₈]·4H₂O was success-fully isolated from an H₂O/DMF solvent combination by evaporation at ambient temperature. The salt crystallizes in the P2₁/n space group. Imidazole, initially used in the synthesis but not present in the product, and DMF solvent appear to affect the synthesis and crystallization as structural-directing agents. In the title compound, the complex cation [Zn(H₂O)₅(DMF)]²⁺ acts as a counter-ion without being directly coordinated to the deca-vanadate anion. An extensive framework of hydrogen bonds integrates the whole architecture as evidenced by X-ray crystallography. The polyoxometalate [V₁₀O₂₈]^6- lies on a center of symmetry while the complex cation [Zn(H₂O)₅(DMF)]²⁺ links three adjacent anions through a set of 2 + 2 + 3 hydrogen bonds.

?-4,4'-Diazenediyldiphthalato-?O:O-bis-[penta-aqua-manganese(II)] tetra-hydrate.

Project description:The dinuclear complex in the title compound, [Mn(2)(C(16)H(6)N(2)O(8))(H(2)O)(10)]·4H(2)O, lies on an inversion center. Two delocalized carboxyl-ate groups are each connected in a monodentate fashion to two similar penta-aqua-manganese units, whereas the other two localized carboxyl-ate groups are uncoordinated. The metal ion has octa-hedral coordination, with the O atom of a carboxyl-ate group and three coordinated water mol-ecules forming the equatorial plane [Mn-O(COO) = 2.143?(4)?Å] and two water mol-ecules occupying the axial positions. The architecture is further consolidated by extensive hydrogen bonds for which coordinated water mol-ecules serve as donors or acceptors.

Hexakis(tetra-aqua-sodium) deca-vanadate(V) dihydrate.

Project description:The title compound, {[Na(H(2)O)(4)](6)[V(10)O(28)]·2H(2)O}(n), crystallized from a H(2)O/THF/CH(3)CN solution (pH ca 6) containing equimolar amounts of NaVO(3) and N-(2-hydroxy-benz-yl)-N-(2-picol-yl)glycine. In the crystal structure, the deca-vanadate [V(10)O(28)](6-) anion ( symmetry) is coordinated, via four terminal oxide ligands of V centres, to two dinuclear [{Na(H(2)O)(3)}(2)(μ-H(2)O)(2)](2+) units. Inter-connection of these aquasodium-ion-sandwiched deca-vanadates to chains parallel to [001] is effected by μ-[{Na(H(2)O)(3)}(2)(μ-H(2)O)(2)](2+) units, bridging adjacent deca-vanadates via O=V. The structure is consolidated by an extensive network of O-H⋯O hydrogen bonds.

Ethyl-enedi-ammonium sodium tetra-kis-[bis-(ethyl-enedi-amine-κ(2) N,N')(oxalato-κ(2) O (1),O (2))cobalt(III)] [penta-hydrogen di(phosphato-octa-deca-tungstate)] tetra-deca-hydrate.

Project description:The title compound, Na(C2H10N2)[Co(C2O4)(C2H8N2)2]4[H5(P2W18O62)2]·14H2O, prepared under hydro-thermal conditions, consists of two Dawson-type [P2W18O62](6-) anions, four isolated [Co(en)2(ox)](+) cations (en = ethyl-enedi-amine and ox = oxalate), one Na(+) cation, one [H2en](2+) cation, and a number of ordered (14) and disordered solvent water mol-ecules. The [P2W18O62](6-) polyoxidometalate anion has site symmetry 1 and contains two structurally distinct types of W atoms: viz. six W atoms on vertical pseudo-mirror planes grouped in two sets of three, and 12 equatorial W atoms that do not lie in the pseudo-mirror planes grouped in two sets of six. In each [Co(en)2(ox)](+) cation, the Co(III) ion is coordinated by four N atoms from two en ligands and two O atoms from the ox ligands, completing a distorted octa-hedral structure. The sodium cation lies on an inversion centre and additionally links the complex cations and anions. In the crystal, the various units are linked by N-H⋯O and O-H⋯O hydrogen bonds, which together with C-H⋯O hydrogen bonds form a three-dimensional structure. The contribution of a region of disordered electron density, possibly highly disordered solvent water mol-ecules, to the scattering was removed with the SQUEEZE option of PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155]. To equilibrate the charges five H(+) ions have been added to the polyoxidometalate. These H(+) ions and the disordered solvent contribution were not included in the reported mol-ecular weight and density.

Tris(ethyl-enediammonium) bis-[(2-amino-ethyl)ammonium] bis-[bis-(μ(5)-hydrogen phosphato)penta-μ(2)-oxido-deca-oxido-penta-molybdenum(VI)] deca-hydrate.

Project description:The title compound, (C(2)H(10)N(2))(3)(C(2)H(9)N(2))(2)[Mo(5)(HPO(4))(2)O(15)]·10H(2)O, was prepared under hydro-thermal conditions at pH 5.0. The structure contains mono- and diprotonated ethyl-enediamine cations, [Mo(5)O(15)(HPO(4))(2)](4-) anions and uncoord-in-ated water mol-ecules. The [Mo(5)O(15)(HPO(4))(2)](4-) hetero-poly-oxometallate anion is made up of five MoO(6) octa-hedra sharing an edge and forming a ring, which is closed by common corners of the terminal MoO(6) octa-hedron. The ring is topped on both sides by two slightly distorted PO(4) tetra-hedra, sharing three corners with three MoO(6) octa-hedra. The terminal oxygen atoms of the PO(4) units are protonated. Together with the anions, the water mol-ecules and the ethyl-enediammonium cations are involved in N-H⋯O and O-H⋯O hydrogen bonding, forming a three-dimensional supra-molecular network.

Penta-ammonium hepta-sodium bis-[penta-kis(μ(2)-oxido)deca-oxido-bis-(μ(5)-phosphato)penta-molybdenum(VI)] henicosa-hydrate.

Project description:The title compound, (NH(4))(5)Na(7)[Mo(5)P(2)O(23)](2)·21H(2)O, was prepared under atmospheric conditions in aqueous solution at room temperature. The structure contains the [Mo(5)P(2)O(23)](6-) heteropolyoxometallate anion, which has been previously reported a number of times with a variety of differing counter-cations. Each anion is built up of five MoO(6) octa-hedra sharing an edge and forming a ring which is closed by common corners of the terminal octa-hedra. The rings are closed on both sides by two asymmetric PO(4) tetra-hedra, sharing three corners with three MoO(6) octa-hedra. The anions are chiral and the two independent anions in the asymmetric unit were arbitarily chosen with the same chirality, but the centrosymmetric crystal contains both enanti-omers. The structure can alternatively be described as a succession of layers parallel to (101), formed by the [Mo(5)P(2)O(23)](6-) anions and linked by sodium chains. Water mol-ecules and ammonium ions fill the remaining space and ensure the cohesion through extensive N-H⋯O and O-H⋯O hydrogen bonding.

Penta-aqua-(di-methyl-formamide)-cobalt(II) sulfate di-methyl-formamide monosolvate.

Project description:The title compound, [Co(C3H7NO)(H2O)5]SO4·C3H7NO, contains five aqua ligands, a Co(II) atom, a sulfate ion and both a coordinating and a non-coordinating di-methyl-formamide (DMF) mol-ecule. The DMF solvent mol-ecule lies between the complex units, which are located along the b axis. The sulfate ion is for charge balance. The Co(II) atom has distorted octa-hedral coordination geometry, being ligated by five aqua ligands and the O atom of the DMF ligand. O-H⋯O hydrogen bonds between the aqua ligands and the sulfate anion and non-coordinating DMF molecule lead to the formation of a three-dimensional network. Since all constituents lie on a mirror plane, the H atoms of all methyl groups and of one of the aqua ligands are equally disordered over two positions.

Bis(tetra-ethyl-ammonium) bis-(dimethyl-formamide)-tetra-kis-(μ-N,2-dioxido-benzene-1-carboximidato)penta-copper(II).

Project description:The title compound, (C(8)H(20)N)(2)[Cu(5)(C(7)H(4)NO(3))(4)(C(3)H(7)NO)(2)], abbreviated as (TEA)(2)[Cu(II)(12-MC(Cu(II) ) (N(shi))-4](DMF)(2) [where TEA is tetra-ethyl-ammonium, shi(3-) is salicyl-hydroximate (or N,2-dioxidobenzene-1-carboximidate) and DMF is N,N-dimethyl-formamide], contains five Cu(II) ions. Four of the Cu(II) ions are members of a metallacrown ring (MC), while the fifth Cu(II) is bound in a central cavity. Two of the ring Cu(II) ions are five-coordinate with distorted square-pyramidal geometry. The coordination sphere is composed of two shi(3-) ligands and one DMF mol-ecule. The other two ring Cu(II) ions and the central Cu(II) ion are four-coordinate with square-planar geometry. The coordination spheres of these ions are only composed of shi(3-) ligands. The charge of the [Cu(II)(12-MC(Cu(II) ) (N(shi))-4](2-) unit is balanced by two uncoordinated TEA(+) countercations. The structure shows severe static disorder with the metallacrown, the tetra-ethyl-ammonium cations and the DMF solvent mol-ecule all disordered over each of two mutually exclusive sites, with occupancy rates for the major moieties of 0.6215 (6) for the metallacrown, 0.759 (3) for the tetra-ethyl-ammonium ion and 0.537 (6) for the DMF mol-ecules. The metallacrown unit is located on a crystallographic inversion center and disordered about a non-crystallographic twofold axis. The DMF mol-ecule and the tetra-ethyl-ammonium ion are disordered about a non-crystallographic twofold axis and pseudo-inversion center, respectively.

Bis[4-(4-pyridyl)pyridinium] μ-4,4'-bipyridine-bis-[tetra-aqua-(4,4'-bipyridine)manganese(II)] bis-(5-sulfonatobenzene-1,3-dicarboxyl-ate) 4,4'-bipyridine solvate penta-deca-hydrate.

Project description:The crystal structure of the title compound, (C(10)H(9)N(2))(2)[Mn(2)(C(10)H(8)N(2))(3)(H(2)O)(8)](C(8)H(3)O(7)S)(2)·C(10)H(8)N(2)·15H(2)O, consists of dinuclear Mn(II) complex cations, sulfonato-benzene-dicarboxyl-ate trianions, 4-(4-pyridyl)pyridinium cations, uncoordin-ated 4,4'-bipyridine and uncoordinated water mol-ecules. One 4,4'-bipyridine mol-ecule bridges two Mn atoms, forming a centrosymmetric dinuclear complex; the mid-point of the C-C bond linking the pyridine rings of the bridging ligand is located on an inversion center. Each Mn(II) atom is coordinated by four water and two 4,4'-bipyridine mol-ecules in a distorted octa-hedral geometry. The Mn(II) atom deviates by 0.591 (5) and 0.209 (2) Å from the mean planes of the coordinated pyridine rings. In the 4-(4-pyridyl)pyridinium cation, the two pyridine rings are twisted with respect to each other, making dihedral angle of 34.78 (17)°. The uncoordinated bipyridine mol-ecule is also centrosymmetric. One of uncoordinated water mol-ecules has site symmetry 2, and the other uncoordinated water mol-ecule is located close to an inversion center and its one H atom is disordered equally over two sites. Extensive π-π stacking between pyridine rings is observed and an extensive hydrogen-bonding network of the types N-H⋯N, O-H⋯N and O-H⋯O is present.

Triclinic modification of tetra-kis-(triethyl-ammonium) dihydrogeno-deca-vanadate(V).

Project description:In the title ammonium polyoxometallate salt, (C(6)H(16)N)(4)[H(2)V(10)O(28)], the anion features O atoms engaged in μ(6)-, μ(3)- and μ(2)-bridging of adjacent V(V) atoms, confering an octa-hedral coordination at each of the twenty unique metal atoms. Two anions are linked by μ(3)- and μ(2)-bridged OH units across a center of inversion, forming a dimer which is linked to the cations by N-H⋯O hydrogen bonds. The cation is disordered over two positions in a 0.776 (4):0.224 (4) ratio in one of the two independent ion pairs in the asymmetric unit, and 0.627 (10):0.373 (10) in the other.

Tetra-aqua-bis-[4-(4H-1,2,4-triazol-4-yl)benzoato-κN]nickel(II) deca-hydrate.

Project description:In the title compound, [Ni(C(9)H(6)N(3)O(2))(2)(H(2)O)(4)]·10H(2)O, the Ni(II) ion lies on a twofold rotation axis and displays a slightly distorted octa-hedral geometry defined by two N atoms from two monodentate 4-(1,2,4-triazol-4-yl)benzoate ligands and four water mol-ecules, two of which also lie on the twofold rotation axis. In the crystal, the complex mol-ecules and uncoordinated water mol-ecules are linked via inter-molecular O-H⋯N and O-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network. π-π inter-actions between the benzene rings provide additional stability of the crystal packing [centroid-centroid distance = 3.792 (2) Å].
