Poly[diaqua-(?(4)-carboxyl-atomethyl-phospho-nato)(?(4)-carb-oxy-methyl-phospho-nato)penta-deca-methyl-penta-tin(IV)].

ABSTRACT: The central Sn(IV) atom of the penta-nuclear title complex, {[Sn(CH(3))(3)](3)O(2)C(CH(2))PO(3)[Sn(CH(3))(3)(H(2)O)](2)HO(2)C(CH(2))PO(3)}, is located on a twofold rotation axis; due to symmetry, the H atom of the carboxyl group of the anion is disordered with a site occupancy of 0.5. The central Sn(IV) atom is bonded to three methyl groups (one of which is disordered about the twofold rotation axis) and is symmetrically trans coordinated by two phospho-nate groups with Sn-O = 2.2665?(12)?Å while the other SnMe(3) residues are asymmetrically trans coordinated with Sn-O = 2.1587?(12) and 2.3756?(13)?Å for one residue and Sn-O = 2.1522?(12) and 2.4335?(12)?Å for the other; the Sn-O distances involving two O atoms trans to carboxyl-ate are longer than those trans to phospho-nate groups. The Sn-C distances lie in a very narrow range [2.112?(2)-2.133?(3)?Å]. The oxyanion behaves as a tetra-coordinating ligand. The bridging mode of the latter leads to the formation of layers parallel to (001) that are inter-connected by O-H?O and C-H?O hydrogen bonds.

Dipotassium diaqua-bis(methyl-enedi-phospho-nato-?O,O')cobaltate(II).

Project description:In the title complex, K(2)[Co(CH(4)O(6)P(2))(2)(H(2)O)(2)], the asymmetric unit contains two K(+) cations and two half-anions in which the Co atoms lie on inversion centers. The Co(II) ions assume an octa-hedral CoO(6) coordination geometry. In the crystal, a three-dimensional network is formed through O-H?O hydrogen-bond inter-actions as well as inter-molecular inter-actions between the K(+) cations and neighbouring O atoms.

Project description:In the title compound, [Co(C(6)H(5)N(2)O(4))(2)(H(2)O)(2)]·2C(3)H(7)NO, the Co(II) ion lies on an inversion center and adopts a slightly distorted CoN(2)O(4) octa-hedral geometry binding two bidentate chelating 5-carb-oxy-2-methyl-1H-imidazole-4-carboxyl-ate (H(2)MIDA(-)) monoanionic ligands and two axial aqua ligands. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link neighboring mol-ecules, generating a two-dimensional framework containing eight-membered H(4)O(4) rings. In addition, the dimethyl-formamide solvent mol-ecules are hydrogen bonded to the two-dimensional framework via the NH groups of the H(2)MIDA(-) ligands.

Project description:In the title compound, [Fe(C(5)H(3)N(2)O(4))(2)(H(2)O)(2)], the Fe(II) ion lies on an inversion centre and is coordinated by two N and two O atoms from two 5-carb-oxy-1H-imidazole-4-carboxyl-ate ligands and two water mol-ecules in a distorted octa-hedral geometry. An intra-molecular O-H?O hydrogen bond occurs. In the crystal, inter-molecular N-H?O and O-H?O hydrogen bonds form a three-dimensional network, which consolidates the packing.

Diaqua-bis(5-carb-oxy-2-methyl-1H-imidazole-4-carboxyl-ato-?N,O)manganese(II).

Project description:The title complex, [Mn(C(6)H(5)N(2)O(4))(2)(H(2)O)(2)], was obtained by hydro-thermal synthesis. The Mn(II) atom, which lies on an inversion centre, displays a slightly distorted octa-hedral geometry. In the crystal packing, complex mol-ecules are linked by inter-molecular O-H?O and N-H?O hydrogen bonds to form a three-dimensional supramolecular structure. The title complex is isostructural with the corresponding cadmium(II) complex [Nie, Wen, Wu, Liu & Liu (2007 ?). Acta Cryst. E63, m753-m755].

cis-Diaqua-bis-[dimethyl (phenyl-sulfonyl-imino)-phospho-nato]cobalt(II).

Project description:In the title diaqua-cobalt complex, [Co(C(8)H(11)NO(5)PS)(2)(H(2)O)(2)], the Co(II) atom is surrounded by six O atoms belonging to the phosphoryl and sulfonyl groups of two deprotonated chelate ligands and two additional O atoms from water mol-ecules which are in cis positions with respect to one another. The coordination environment of cobalt can be described as a distorted octa-hedron. O-H⋯O hydrogen bonds between the water and sulfonyl O atoms of neighboring mol-ecules form chains running parallel to [010]. Two methoxy groups attached to one phosphorus are disordered over two sets of sites in a 0.6:0.4 ratio.

catena-Poly[[(diaqua-zinc)-?-3-carb-oxy-pyrazine-2-carboxyl-ato-?N,O;N,O] nitrate].

Project description:The crystal structure of the title compound, {[Zn(C(6)H(3)N(2)O(4))(H(2)O)(2)]NO(3)}(n), is built of zigzag cationic chains propagating in [010] with nitrate anions located in the space between the chains. The Zn(II) ion is coordinated by N and O atoms of two symmetry-related ligands in equatorial sites, and by two water O atoms at the axial sites of a distorted octa-hedron. One carboxyl-ate group of the ligand remains protonated, serving as a donor in a short intra-molecular O-H?O hydrogen bond. The coordinated water mol-ecules are donors and the nitrate O atoms act as acceptors in a network of O-H?O hydrogen bonds.

catena-Poly[[diaqua-lithium]-?-[rac-cis-(2-carb-oxy-cyclo-hexane-1-carboxyl-ato-?O:O]].

Project description:In the structure of the title compound, [Li(C(8)H(11)O(4))(H(2)O)(2)](n), the distorted tetra-hadral LiO(4) coordination sphere comprises two water mol-ecules and two carboxyl O-atom donors from separate bridging cis-2-carb-oxy-cyclo-hexane-1-carboxyl-ate monoanions [Li-O = 1.887?(4)-1.946?(3)?Å], giving chain substructures which extend along [010]. Water-water and water-carboxyl O-H?O hydrogen bonds stabilize these chain structures and provide inter-chain links, resulting in a two-dimensional layered structure extending parallel to (100).
