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

ABSTRACT: 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.

Tris(4,4'-di-tert-butyl-2,2'-bipyridine-?N,N')molybdenum(II) ?(6)-oxido-dodeca-?(2)-oxido-hexa-oxidohexa-molybdate(VI) acetonitrile tetra-solvate.

Project description:The asymmetric unit of the title compound, [Mo(C(18)H(24)N(2))(3)][Mo(6)O(19)]·4CH(3)CN, comprises an [Mo(di-t-Bu-bipy)(3)](2+) cation (di-t-Bu-bipy is 4,4'-di-tert-butyl-2,2'-bipyridine), two halves of Lindqvist-type [Mo(6)O(19)](2-) anions (with each anion completed by the application of a center of inversion) and four acetonitrile solvent mol-ecules. The geometry around the metal atom of the cation resembles a distorted octa-hedron, with each of the three di-t-Bu-bipy ligands being almost planar [deviation from planarity < 6.3?(2)°]. Supra-molecular inter-actions, namely Mo=O??, C N??, C-H?O and C-H?N, along with electrostatic forces, mediate the crystal packing. Two of the tert-butyl groups are affected by rotational disorder which was modeled over two distinct positions with major site occupancies of 0.707?(9) and 0.769?(8).

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.

?-Oxalato-bis-[bis-(2,2'-bipyridine)-manganese(II)] bis(perchlorate) 2,2'-bipyridine solvate.

Project description:The unit cell of the title compound, [Mn(2)(C(2)O(4))(C(10)H(8)N(2))(4)](ClO(4))(2)·C(10)H(8)N(2), consists of a binuclear cation, two perchlor-ate anions, and one solvent 2,2'-bipyridine (bpy) mol-ecule. In the complex cation [Mn(2)(C(2)O(4))(C(10)N(2)H(8))(4)](2+), two Mn(II) atoms are bridged by a bis-(bidentate) oxalate ligand, each Mn(II) atom being further coordinated by two bpy ligands in a distorted octa-hedral geometry. The distance between the two six-coordinated metal atoms is 5.583?(1)?Å. ?-? stacking inter-actions [inter-planar distances between bpy rings = 3.739?(1)?Å] are essential to the supramolecular assembly. There are extensive inter-ionic C-H?O inter-actions between the cations and between the cation and anion. Three of the four perchlorate O atoms are disordered over two sets of sites with occupancy ratios of 0.852?(6):0.148?(6).

?-Oxido-bis-[chlorido(4,4'-di-tert-butyl-2,2'-bipyridine-?N,N')dioxido-molybdenum(VI)] 0.2-hydrate.

Project description:The title hydrate, [Mo(2)Cl(2)O(5)(C(18)H(24)N(2))(2)]·0.2H(2)O, has been isolated as the oxidation product of [Mo(?(3)-C(3)H(5))Cl(CO)(2)(di-t-Bu-bipy)] (where di-t-Bu-bipy is 4,4'-di-tert-butyl-2,2'-bipyridine). A ?-oxide ligand bridges two similar MoCl(di-t-Bu-bipy)O(2) units, having the terminal oxide ligands mutually cis, and the chloride and ?-oxide trans to each other. In the binuclear complex, the coordination geometries of the metal atoms can be described as highly distorted octa-hedra. Individual complexes co-crystallize with a partially occupied water mol-ecule of crystallization (occupancy factor = 0.20; H atoms not located), with the crystal packing being mediated by the need to effectively fill the available space. A number of weak C-H?O and C-H?Cl inter-actions are present.

Bis(4,4'-bipyridinium) dodeca-tungsto-silicate 4,4'-bipyridine hexa-hydrate.

Project description:The title compound, (C(10)H(10)N(2))(2)[SiW(12)O(40)]·C(10)H(8)N(2)·6H(2)O or (4,4'-bipyH(2))(2)[SiW(12)O(40)].(4,4'-bipy)·6H(2)O (4,4'-bipy is 4,4'-bipyridine), was prepared under hydro-thermal conditions. The asymmetric unit contains a discrete Keggin-type [SiW(12)O(40)](4-) anion (located on a twofold axis), one 4,4'-bipy (located on a twofold axis), two (4,4'-bipyH(2))(2+) cations and six uncoordinated water mol-ecules. The polyoxoanion is constructed from a central SiO(4) tetra-hedron which shares its O atoms with four trinuclear W(3)O(13) groups, each of which is made up of three edge-sharing WO(6) octa-hedra. The water mol-ecules and [SiW(12)O(40)](4-) anions are linked through hydrogen bonds.
