Hexa-kis-(dimethyl sulfoxide-?O)calcium ?(6)-oxido-dodeca-kis-?(2)-oxido-hexa-oxido-hexa-tungstate(VI).

ABSTRACT: In the title compound, [Ca(C(2)H(6)OS)(6)][W(6)O(19)], the cation and anion both have a crystallographically imposed centre of symmetry. The Ca(II) atom in the cation is coordinated by six O atoms from six dimethyl sulfoxide ligands in a distorted octa-hedral geometry. The [W(6)O(19)](2-) isopolyanion possesses the well-known Lindqvist structure in which each W(VI) atom is coordinated by four ?(2)-O, one terminal O and one ?(6)-O atom.

Octa-kis(dimethyl sulfoxide-κO)cerium(III) μ(6)-oxido-dodeca-μ(2)-oxido-hexa-oxidohexa-molybdate(VI) dimethyl sulfoxide tetrasolvate.

Project description:The title complex, [Ce(C(2)H(6)OS)(8)](2)[Mo(6)O(19)](3)·4C(2)H(6)OS, was obtained as a byproduct of the reaction of [(C(4)H(9))(4)N](2)[Mo(6)O(19)] with Ce(NO(3))(3)·6H(2)O and phthalic acid in dimethyl-sulfoxide solution. The asymmetric unit consists of a complex [Ce(C(2)H(6)OS)(8)](3+) cation, one and a half of the Lindqvist-type [Mo(6)O(19)](2-) polyanions and two dimethyl-sulfoxide solvent mol-ecules; the half polyanion lies on an inversion center. The Ce(3+) ion is coordinated by eight dimethyl-sulfoxide ligands through the O atoms in the form of a distorted square antiprism. The Ce-O bond lengths range from 2.429 (6) to 2.550 (5) Å. The cohesion of the structure is ensured by S⋯O [3.115 (6), 3.242 (10) and 3.12 (3) Å], O⋯O [3.037 (10) Å] and C-H⋯O inter-actions between cations and anions. The S and C atoms of a dmso ligand are disordered over three sites in a 0.45:0.30:0.25 ratio. The dimethyl-sulfoxide solvent mol-ecules are highly disordered and could not be modelled successfully; their contribution was therefore removed from the refinement using the SQUEEZE routine in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155]. Potential solvent-accessible voids of 500.0 Å(3) occur in the crystal structure.

(?-Oxalato-?O,O:O,O)bis-[bis-(2,2'-bipyridine-?N,N')cobalt(II)] ?(6)-oxido-dodeca-?(2)-oxido-hexa-oxido-hexa-tungstate(VI).

Project description:The asymmetric unit of the title compound, [Co(2)(C(2)O(4))(C(10)H(8)N(2))(4)][W(6)O(19)], consists of one half of the complex [Co(2)(C(2)O(4))(C(10)H(8)N(2))(4)](2+) cation and one half of the Lindqvist-type [W(6)O(19)](2-) isopolyanion. Both constituents are completed by crystallographic inversion symmetry. In the dimeric cation, the Co(II) atom is surrounded in a distorted octa-hedral coordination by four N atoms from two chelating 2,2'-bipyridine ligands and by two O atoms from the chelating oxalate anion. The Lindqvist-type anion exhibits the characteristic W-O bond-length distribution, with the shortest bonds being the W-O(terminal) bonds and the longest being those to the central O atom.

Bis[bis-(1,10-phenanthroline-?N,N')copper(I)] ?(6)-oxido-dodeca-kis-?(2)-oxido-hexa-oxidohexa-tungsten(VI).

Project description:The title compound, [Cu(C(12)H(8)N(2))(2)](2)[W(6)O(19)], consists of two [Cu(phen)(2)](+) cations (phen = 1,10-phenanthroline) and one typical [W(6)O(19)](2-) isopolyanion. The Cu(I) atom is coordinated by four N atoms from two bidentate chelating phen ligands in a distorted tetra-hedral geometry. The hexa-tungstate anion, lying on an inversion center and possessing the well known Lindqvist structure, is formed by six edge-sharing WO(6) octa-hedra, thus exhibiting an approximate O(h) symmetry. Three kinds of O atoms exist in the hexa-tungstate, viz. terminal O(a), bridging O(b) and central O(c) atoms. Besides the electrostatic effects between the anions and cations, weak C-H?O hydrogen bonds exist between the phen ligands and O(a) or O(b) atoms. The mean inter-planar distances of 3.485?(1) and 3.344?(1)?Å indicate ?-? stacking inter-actions between neighboring phen ligands. These weak hydrogen bonds and ?-? stacking inter-actions lead to a two-dimensional network.

Tetra-imidazolium hexa-?(4)-oxido-dodeca-?(2)-oxido-dodeca-oxidohexa-arsenate(III)hexa-molybdenum(VI)cuprate(II).

Project description:The title compound, (C(3)H(5)N(2))(4)[As(6)CuMo(6)O(30)], is made up of a centrosymmetric anionic cluster and four imidazolium cations. In the cluster, the central Cu(II) atom is six-coordinated and lies on an inversion center. Adjacent clusters are linked via N-H?O hydrogen bonds between the imidazole cations and polyoxidoanions into a three-dimensional supra-molecular architecture.

Hexa-kis-(dimethyl sulfoxide-?O)zinc(II) poly-iodide.

Project description:The title compound, [Zn{(CH3)2SO}6]I4, is a one-dimensional supra-molecular polymer along a threefold rotation axis of the space group. It is built up from discrete [Zn{(CH3)2SO}6](2+) units connected through non-classical hydrogen bonds to linear I4 (2-) polyiodide anions (C-H?I = 3.168?Å). The Zn(II) ion in the cation has an octa-hedral coordination geometry, with all six Zn-O bond lengths being equivalent, at 2.111?(4)?Å. The linear polyiodide anion contains a neutral I2 mol-ecule weakly coordinated to two iodide ions.

Tris(2,2'-bipyridine)-cobalt(II) μ(6)-oxido-dodeca-μ(2)-oxido-hexa-oxidohexa-molydate(VI).

Project description:In the title compound, [Co(C(10)H(8)N(2))(3)][Mo(6)O(19)], the Co(2+) cation is surrounded in a distorted octa-hedral coordination by six N atoms from three 2,2'-bipyridine ligands. The distribution of Mo-O bond lengths in the Lindqvist isopolyanion is consistent with other structures containing the same unit. In the crystal, the cations and anions are linked by C-H⋯O inter-actions.

One of the two crystallographiclly independent morpholinium cations is half-occupied. Inter-molecular N-H?O and O-H?O hydrogen bonds link the cations, polyoxoanions and uncoordinated water mol-ecules.

Crystal structure of octa-kis-(N,N-di-methyl-formamide-κO)europium(III) tetra-cosa-μ2-oxido-dodeca-oxido-μ12-phosphato-dodeca-molybdate(VI).

Project description:In the title salt, [Eu(C3H7NO)8][PMo12O40], the asymmetric unit comprises one α-Keggin-type [PMo12O40](3-) polyoxidometalate anion and one distorted dodeca-hedral [Eu(C3H7NO)8](3+) complex cation. In the crystal, the isolated polyoxidometalate anions are packed into hexa-gonally arranged rows extending parallel to [001]. The complex cations are situated between the rows and are linked to the neighbouring anions through weak C-H⋯O hydrogen-bonding inter-actions, leading to the formation of a three-dimensional network structure.

Hexa-kis-(dimethyl sulfoxide-?O)thallium(III) trinitrate.

Project description:The title compound, [Tl(C(2)H(6)OS)(6)](NO(3))(3), consists of six dimethyl sulfoxide (DMSO) mol-ecules coordinated to a Tl(III) atom, which lies on a axis, and three nitrate anions (3. symmetry) to neutralize the charge. The coordination polyhedron around the Tl(III) atom is octa-hedral, defined by six O atoms of the DMSO mol-ecules. In the crystal structure, C-H?O hydrogen bonds are observed. One of the nitrate groups exhibits half-occupation.

Hexa-kis-(dimethyl-formamide-κO)manganese(II) μ-oxido-bis-[trichlorido-ferrate(III)].

Project description:The title compound, [Mn(C(3)H(7)NO)(6)][Fe(2)Cl(6)O], was obtained unintentionally as a product of an attempted synthesis of heterometallic complexes with Schiff base ligands using manganese powder and FeCl(3)·6H(2)O as starting materials. In the [Fe(2)OCl(6)](2-) anion, the O atom and the Fe atom occupy positions with site symmetry [Formula: see text] and 3, respectively, resulting in a linear Fe-O-Fe angle and a staggered conformation. The octa-hedrally surrounded cation (site symmetry [Formula: see text]) and the [Fe(2)Cl(6)O](2-) anion are alternately stacked along [001].
