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

ABSTRACT: 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)(?-H(2)O)(2)](2+) units. Inter-connection of these aquasodium-ion-sandwiched deca-vanadates to chains parallel to [001] is effected by ?-[{Na(H(2)O)(3)}(2)(?-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.

Project description:In the title compound, (C(2)H(8)N)(6)[V(10)O(28)]·H(2)O, the [V(10)O(28)](6-) polymetalate anion has crystallographic mirror symmetry with six V atoms and 12 O atoms lying on the mirror plane. Each of the V(V) atoms adopts a distorted octa-hedral geometry. Eight terminal O atoms are bonded to V(V) atoms with double bonds and the others act as bridging atoms. In the crystal structure, a network of N-H?O and O-H?O hydrogen bonds helps to establish the packing.

Nonapiperidinium monohydrogen deca-vanadate tetra-nitrate.

Project description:The title compound, (C(5)H(12)N)(9)[HV(10)O(28)](NO(3))(4), contains a monoprotonated deca-vanadate polyanion which lies on an inversion center. All the piperidinium cations adopt chair conformations. In the crystal structure, inter-molecular N-H?O hydrogen bonds form chains along [001]. As well as half of a polyanion, the asymmetric unit contains one full and two half-occupancy nitrate ions and four full occupancy and one half-occupancy piperidinium cations; the half-occupancy piperidinium cation is disordered over two general sites with occupancies of 0.32 and 0.18, and is, in turn, disordered over an inversion center.

Project description:In the title compound, (C(5)H(7)N(2))(6)[V(10)O(28)]·2H(2)O, the [V(10)O(28)](6-) anion is generated by crystallographic inversion symmetry and each of the five vanadium centres adopts a distorted VO(6) octa-hedral geometry. In the crystal structure, a network of N-H?O, N-H?(O,O) and O-H?O hydrogen bonds helps to establish the packing.

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

Project description: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.

Tetrakis(2,6-di-methyl-pyridinium) di-hydrogen deca-vanadate dihydrate.

Project description:The structure of the title compound, (C7H10N)4[H2V10O28]·2H2O, was solved from a non-merohedrally twinned crystal (ratio of twin components ?0.6:0.4). The asymmetric unit consists of one-half deca-vanadate anion (the other half completed by inversion symmetry), two 2,6-di-methyl-pyridinium cations and one water mol-ecule of crystallization. In the crystal, the components are connected by strong N-H?O and O-H?O hydrogen bonds, forming a supra-molecular chain along the b-axis direction. There are weak C-H?O inter-actions between the chains.

Tetra-aqua-bis(orotato-?O)cobalt(II) dihydrate.

Project description:In the title Co(II) complex, [Co(C(5)H(3)N(2)O(4))(2)(H(2)O)(4)]·2H(2)O, the Co(II) ion is located on an inversion center and is coordinated by two orotate (2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate) anions and four water mol-ecules in a slightly distorted octa-hedral geometry. The dihedral angle between the carboxyl-ate group and the attached orotate ring is 1.2?(3)°. In the crystal structure, inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network. ?-? contacts between the orotate rings [centroid-centroid distances = 3.439?(2) and 3.438?(2)?Å] further stabilize the structure.

(meso-5,7,7,12,14,14-Hexamethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-4,11-diene)nickel(II) dibromide dihydrate.

Project description:The asymmetric unit of the title compound, [Ni(C(16)H(32)N(4))]Br(2)·2H(2)O, consists of one half [Ni(C(16)H(32)N(4))](2+) cation, one Br(-) anion and one water mol-ecule of crystallization.

In the crystal structure, the cations, anions and water mol-ecules are linked via inter-molecular N-H⋯Br and O-H⋯Br hydrogen bonds, forming discrete chains with set-graph motif D(2)D(2) (2)(7)D(2) (1)(3)D(3) (2)(8). The water mol-ecules and Br(-) ions are linked with set-graph motif R(4) (2)(8).

Project description:In the title compound, {[Fe(C(2)N(10))(H(2)O)(4)]·2H(2)O}(n), the coordin-ation geometry around the Fe(II) atom, which lies on a center of inversion, is distorted octa-hedral, with bonds to four O atoms and two N atoms. The azotetra-zolate ligand displays a bridging coordination mode, forming an infinite zigzag chain. Inter-molecular O-H?O and O-H?N hydrogen bonding and offset face-to-face ?-? stacking inter-actions [centroid-centroid distance = 3.4738?(13)?Å] lead to a three-dimensional network.

Project description:In the title mononuclear complex, [Cd(C(12)H(8)N(2))(H(2)O)(4)]SO(4)·2H(2)O, the coordination geometry around the Cd(II) atom is a distorted octa-hedron, with two aqua ligands occupying the axial positions. Inter-molecular O-H?O hydrogen bonds lead to the formation of a two-dimensional layer structure parallel to (001). The layers are connected by ?-? inter-actions between the pyridyl and benzene rings of the phenanthroline ligands [centroid-centroid distances = 3.591?(1) and 3.610?(1)?Å].
