Dipotassium tetra-aqua-bis-[3,5-bis-(dicyano-methyl-ene)cyclo-pentane-1,2,4-trionato(1-)-?N]cobaltate(II).

ABSTRACT: The title structure, K(2)[Co(C(11)N(4)O(3))(2)(H(2)O)(4)], is isotypic with K(2)[Fe(C(11)N(4)O(3))(2)(H(2)O)(4)]. The Co(II) atom is in a distorted octa-hedral CoN(2)O(4) geometry, forming a dianionic mononuclear entity. Each dianionic unit is associated with two potassium cations and inter-acts with adjacent units through O-H?N and O-H?O hydrogen bonds.

Crystal structure of tetra-aqua-bis(3,5-di-amino-4H-1,2,4-triazol-1-ium)cobalt(II) bis-[bis-(pyridine-2,6-di-carboxyl-ato)cobaltate(II)] dihydrate.

Project description:The asymmetric unit of the title compound, [Co(C2H6N5)2(H2O)4][Co(C7H3NO4)2]2·2H2O, features 1.5 Co(II) ions (one anionic complex and one half cationic complex) and one water mol-ecule. In the cationic complex, the Co(II) atom is located on an inversion centre and is coordinated by two triazolium cations and four water mol-ecules, adopting an octa-hedral geometry where the N atoms of the two triazolium cations occupy the axial positions and the O atoms of the four water mol-ecules the equatorial positions. The two triazole ligands are parallel offset (with a distance of 1.38?Å between their planes). In the anionic complex, the Co(II) ion is six-coordinated by two N and four O atoms of the two pyridine-2,6-di-carboxyl-ate anions, exhibiting a slightly distorted octa-hedral coordination geometry in which the mean plane of the two pyridine-2,6-di-carboxyl-ate anions are almost perpendicular to each other, making a dihedral angle of 85.87?(2)°. In the crystal, mol-ecules are linked into a three-dimensional network via C-H?O, C-H?N, O-H?O and N-H?O hydrogen bonds.

([2.2.2]Cryptand-?(6)O)potassium (?(4)-cyclo-octa-diene)bis-(?(2)-pyrene)cobaltate(1-) pentane hemisolvate.

Project description:The cation, anion, and solvent in the title compound, [K(C(18)H(36)N(2)O(6))][Co(C(8)H(12))(C(16)H(10))(2)]·0.5C(5)H(12), are well separated. The pentane solvent mol-ecules are found in channels along [100] and were modeled as disordered over crystallographic inversion centers. Using the mid-points of the coordinated olefins, the angle between the C(py)/C(py)-Co-C(py)/C(py) and the C(cod)/C(cod)-Co-C(cod)/C(cod) planes (py is pyrene and cod is cyclo-octa-diene) is 67.6?(2)°. Thus, the overall geometry of the coordination sphere around cobalt is best described as distorted tetra-hedral.

Project description:The Ni(II) atom in the title compound, [Ni(C(12)H(8)N(5))(2)(H(2)O)(4)]·2H(2)O, lies on a center of inversion and is coordinated by the N atoms of two 3,5-di-4-pyridine-1,2,4-triazolate ligands and by four water O atoms in a slightly distorted octa-hedral geometry. The coordinated and uncoordinated water mol-ecules inter-act with the N-heterocycles through O-H?N and O-H?O hydrogen bonds, generating a three-dimensional supra-molecular architecture.

Bis[triaqua-(1H-1,2,4-triazole-3,5-dicarboxyl-ato-?O,N)copper(II)] di-?-aqua-bis-[diaqua-(1H-1,2,4-triazole-3,5-dicarboxyl-ato-?O,N)copper(II)].

Project description:In the title compound, [Cu(C(4)HN(3)O(4))(H(2)O)(3)](2)[Cu(2)(C(4)HN(3)O(4))(2)(H(2)O)(6)], both monomeric and dimeric mol-ecules are present in the solid state. In the monomeric compound, the Cu(II) atom is five-coordinated in a square-pyramidal configuration by one O atom and one N atom from one 1H-1,2,4-triazole-3,5-dicarboxyl-ate (TZDCA(2-)) ligand and three O atoms from water mol-ecules. In the centrosymmetric binuclear complex, each Cu(II) atom is six-coordinated in an octa-hedral geometry by one O atom and one N atom from one TZDCA(2-) ligand and four O atoms from water mol-ecules, two of which bridge the Cu(II) atoms. In the structure, there are intra-molecular O-H?O and N-H?O hydrogen bonds, and in the crystal, inter-molecular O-H?O, O-H?N and N-H?O hydrogen bonds link symmetry-related mol-ecules, forming a three-dimensional supra-molecular structure.

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.

Dipotassium hexa-aqua-nickel(II) bis-[hexa-fluoridozirconate(IV)].

Project description:Single crystals of the title compound, K(2)[Ni(H(2)O)(6)][ZrF(6)](2), were grown by slow evaporation of a 40% aqueous HF solution in which a stoichiometric mixture of NiCl(2)·6H(2)O, ZrF(4) and KCl was dissolved. The monoclinic structure is isotypic with its K(2)Cu, K(2)Zn, Cs(2)Zn and Cs(2)Cu analogues. The structure is built up from isolated, slightly elongated octa-hedral [Ni(H(2)O)(6)](2+) complex cations (symmetry ) and dimeric [Zr(2)F(12)](4-) complex anions (symmetry ) that are also isolated from each other. The [Zr(2)F(12)](4-) anion results from the association of two distorted penta-gonal-bipyramidal [ZrF(7)] coordination polyhedra by sharing an equatorial edge passing through an inversion center of the unit cell. Both isolated [Ni(H(2)O)(6)](2+) and [Zr(2)F(12)](4-) complex ions are situated in planes parallel to (010). They are connected by the eight-coordinated K(+) ions into a three-dimensional structure. An intricate O-H?F hydrogen-bonding network consolidates the structure.

Poly[?-aqua-bis-(?5-2,4-di-chloro-benzoato)dipotassium].

Project description:In the title compound, [K2(C7H3Cl2O2)2(H2O)] n , the potassium salt of 2,4-di-chloro-benzoic acid, the repeating unit in the polymeric structure consists of two identical irregular KO6Cl units related by twofold rotational symmetry, linked by a bridging water mol-ecule lying on the twofold axis. The coordination polyhedron about the K(+) ion comprises a carboxyl-ate O atom and a Cl-atom donor from a bidentate chelate ligand inter-action, four O-atom donors from a doubly bridging bidentate carboxyl-ate O,O'-chelate inter-action and the water mol-ecule. A two-dimensional polymeric structure lying parallel to (100) is generated through a series of conjoined cyclic bridges between K(+) ions and is stabilized by water-carboxyl-ate O-H?O hydrogen-bonding inter-actions.
