?-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.

Project description:The title binuclear complex, [Co(2)(C(8)H(3)NO(6))(2)(C(10)H(8)N(2))(3)(H(2)O)(6)], has been synthesized hydro-thermally from 3-nitro-phthalic acid (H(2)NPA), Co(NO(3))(2)·6H(2)O and 4,4'-bipyridine (4,4'-bipy). The mol-ecule of the complex occupies a special position on an inversion centre. The Co(II) atom has a slightly distorted octa-hedral environment formed by two N atoms from two 4,4'-bipy ligands, one carboxyl-ate O atom from NPA, and three O atoms of water mol-ecules. An extensive O-H?O and N-H?O hydrogen-bonding system links mol-ecules of the complex into a three-dimensional network.

The 4,4'-bipyridine and the two acetic acid mol-ecules are further connected through weak C-H?O hydrogen bonds to form a supra-molecular two-dimensional network parallel to the (001) plane. The two pyridine rings make a dihedral angle of 31.8?(1)°.

Bis[4-(4-pyridyl)pyridinium] ?-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 ?-? 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.

In the crystal, the coordinated water mol-ecules, isothio-cyanate ions and solvent 4,4'-bipyridine mol-ecules are linked by O-H?S and O-H?N hydrogen bonds into layers parallel to the ab plane.

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.

Aqua-[N'-(3-eth-oxy-2-oxidobenzyl-?O)furan-1-carbohydrazidato-?N',O]dioxido-molybdenum(VI)-4,4'-bipyridine (2/1).

Project description:The Mo(VI) atom in the title co-crystal, [Mo(C(14)H(12)N(2)O(4))O(2)(H(2)O)]·0.5C(10)H(8)N(2), is O,N,O'-chelated by the deprotonated Schiff base and coordinated by the oxide and water O atoms in an octa-hedral geometry. The five-membered chelate ring is planar (r.m.s. deviation = 0.019?Å), but the six-membered chelate ring is puckered (r.m.s. deviation = 0.108?Å). Two mononuclear mol-ecules are linked across a center of inversion by an O-H(water)?O hydrogen bond; adjacent dinuclear units are linked by an water-4,4'-bipyridine O-H?N hydrogen bond, generating a linear chain structure. The 4,4'-bipyridine mol-ecule is disordered over two positions in a 1:1 ratio.

catena-Poly[[[tetra-aqua-cobalt(II)]-μ-4,4'-bipyridine-κN:N'] bis-(perchlorate) 4,4'-bipyridine disolvate dihydrate].

Project description:In the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](ClO(4))(2)·2C(10)H(8)N(2)·2H(2)O}(n), slightly distorted octa-hedrally coordinated Co(II) ions situated on inversion centers are linked into polycationic chains through 4,4'-bipyridine tethering ligands. These are connected into supra-molecular layers by hydrogen bonding involving aqua ligands, perchlorate anions and uncoordinated water mol-ecules. A twofold inter-penetrated primitive cubic supra-molecular network is formed by the inter-action of pseudo-layers by hydrogen bonding between aqua ligands and unligated 4,4'-bipyridine mol-ecules.
