Hexakis(dimethyl-ammonium) di-?(6)-oxido-tetra-?(3)-oxido-tetra-deca-?(2)-oxido-octa-oxidodeca-vanadate(V) monohydrate.

ABSTRACT: 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.

Tetra-ammonium bis-(metforminium) di-μ6-oxido-tetra-μ3-oxido-tetra-deca-μ2-oxido-octa-oxidodeca-vanadium(V) hexa-hydrate.

Project description:The title compound, (NH4)4(C4H12N5)2[V10O28]·6H2O, crystallizes with the deca-vanadate anion placed on an inversion centre in space group P . This anion is surrounded by a first shell of ammonium cations and water mol-ecules, forming efficient N-H⋯O and O-H⋯O hydrogen bonds. A second shell includes metforminium monocations with a twisted geometry, also forming numerous inter-molecular hydrogen bonds. The complex three-dimensional network of non-covalent inter-actions affords a crystal structure in which the cations and anions are densely packed.

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)(?-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.

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.

Bis[tris-(ethyl-enediamine-?N,N')cobalt(III)] octa-kis-?-(3)-oxido-hexa-deca-?(2)-oxido-tetra-deca-oxido-?(12)-tetra-oxo-silicato-octa-molybdenum(VI)hexa-vanadium(IV,V) hexa-hydrate.

Project description:The title compound, [Co(C(2)H(8)N(2))(3)](2)[SiMo(8)V(4)O(40)(VO)(2)]·6H(2)O, was prepared under hydro-thermal conditions. The asymmetric unit consists of a transition metal complex [Co(en)(3)](3+) cation (en is ethyl-enediamine), one half of an [SiMo(8)V(4)O(40)(VO)(2)](6-) heteropolyanion, two solvent water mol-ecules in general positions and two half-mol-ecules of water located on a mirror plane. In the complex cation, the Co(3+) ion is in a distorted octa-hedral coordination environment formed by six N atoms of the three chelating en ligands. One of the en ligands exhibits disorder of its aliphatic chain over two sets of sites of equal occupancy. The [SiMo(8)V(4)O(40)(VO)(2)](6-) heteropolyanion is a four-electron reduced bivanadyl-capped ?-Keggin-type molybdenum-vanadium-oxide cluster. In the crystal, it is located on a mirror plane, which results in disorder of the central tetra-hedral SiO(4) group: the O atoms of this group occupy two sets of sites related by a mirror plane. Furthermore, all of the eight ?(2)-oxide groups are also disordered over two sets of sites with equal occupancy. There are extensive inter-molecular N-H?O hydrogen bonds between the complex cations and inorganic polyoxidoanions, leading to a three-dimensional supra-molecular network.

Dichloridodi-μ(2)-hydroxido-di-μ(3)-oxido-octa-phenyl-tetra-tin(IV) dimethyl sulfoxide disolvate.

Project description:In the centrosymmetric tetra-nuclear title mol-ecule, [Sn(4)(C(6)H(5))(8)Cl(2)O(2)(OH)(2)]·2C(2)H(6)OS, the two independent tin(IV) atoms show distorted trigonal-bipyramidal SnC(2)O(3) and SnC(2)O(2)Cl coordination geometries. The four tin(IV) atoms are bridged by the hydroxo and oxo ligands, forming a ladder-like array of three edge-connected Sn(2)O(2) squares. The solvent mol-ecules are linked to the tetra-nuclear mol-ecule via O-H⋯O hydrogen bonds.

Bis{[amino-(iminium-yl)meth-yl]urea} tetra-kis-{2-[(di-methyl-amino)(iminium-yl)meth-yl]guanidine} di-μ6-oxido-tetra-μ3-oxido-tetra-deca-μ2-oxido-octa-oxidodeca-vanadium(V) tetra-hydrate.

Project description:The title compound, (C4H12N5)4(C2H7N4O)2[V10O28]·4H2O, is a by-product obtained by reacting ammonium metavanadate(V), metformin hydro-chloride and acetic acid in the presence of sodium hypochlorite, at pH = 5. The crystal structure comprises a deca-vanadate(V) anion (V10O28)6- lying on an inversion centre in space group P , while cations and solvent water mol-ecules are placed in general positions, surrounding the anion, and forming numerous N-H⋯O and O-H⋯O hydrogen bonds. Metforminium (C4H12N5)+ and guanylurea (C2H7N4O)+ cations display the expected shape. Inter-estingly, in physiology the latter cation is known to be the main metabolite of the former one. The reported structure thus supports the role of sodium hypochlorite as an oxidizing reagent being able to degrade metformin hydro-chloride to form guanylurea.

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.

Tetra-quinolinium ditelluro(VI)octa-vanadate(V) octa-hydrate.

Project description:In the title compound, (C9H8N)4[Te2V8O28]·8H2O, the com-plete heteropolyanion is generated by a crystallographic inversion centre. One of the two quniolinium ions forms an N-H?Op (p = polyoxidometallate) hydrogen bond and the other an N-H?Ow (w = water) hydrogen bond. The water mol-ecules further link the components by O-H?Op and O-H?Ow hydrogen bonds. A number of C-H?O inter-actions and aromatic ?-? stacking inter-actions [shortest centroid-centroid separation = 3.541?(7)?Å] are also observed. Together, these generate a three-dimensional network.
