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

ABSTRACT: 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 salt, (NH(4))(2)[Co(CH(4)O(6)P(2))(2)(H(2)O)(2)], the methyl-ene-diphospho-nate acts as a bidentate ligand and the Co(II) ion (site symmetry ) assumes an octa-hedral CoO(6) coordination geometry.

Bis(2-methyl-anilinium) diaqua-bis[dihydrogendiphosphato(2-)]cobaltate(II).

Project description:In the title cobalt(II) complex with 2-methyl-anilinium and diphosphate, (C(7)H(10)N)(2)[Co(H(2)P(2)O(7))(2)(H(2)O)(2)], a three-dimensional network is built up from anionic layers of [Co(H(2)P(2)O(7))(2)(H(2)O)(2)](2-) units and 2-methyl-anilinium cations located between these layers. The dihydrogendiphosphate groups present a bent eclipsed conformation, while the Co(2+) ions lie on inversion centers. An intricate network of O-H?O and N-H?O hydrogen bonds is established between the different components, assuring the cohesion of the network with other inter-actions, being of electrostatic and van der Waals nature.

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.

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

Project description: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.

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

Project description: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.

Bis(2-amino-6-methyl-pyridinium) trans-diaqua-bis-(pyrazine-2,3-dicarboxyl-ato)cobaltate(II) octa-hydrate.

Project description:The title compound, (C(6)H(9)N(2))(2)[Co(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·8H(2)O, was obtained by the reaction of CoCl(2)·6H(2)O with 1,4-pyrazine-2,3-dicarb-oxy-lic acid and 2-amino-6-methyl-pyridine in aqueous solution (molar ratio 1:2:2). The Co(II) ion is situated on an inversion centre and is coordinated by two O and two N atoms of two symmetry-related 1,4-pyrazine-2,3-dicarboxyl-ate ligands and two water mol-ecules and has a disorted octa-hedral coordination environment. The asymmetric unit also contains four water mol-ecules. In the crystal, extensive inter-molecular classical N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.490 (1) Å] connect the various components, forming a three-dimensional network.

Bis(tetra-phenyl-phospho-nium) tetra-chlorido-cobaltate(II).

Project description:The title compound, (C24H20P)2[CoCl4], was prepared under hydro-thermal conditions. In the crystal, the tetra-phenyl-phospho-nium cations are linked by pairs of weak C-H⋯π inter-actions into supra-molecular dimers; the Co(II) cations lie on twofold rotation axes and the tetra-hedral [CoCl4](2-) anions are linked with the tetra-phenyl-phospho-nium cations via weak C-H⋯Cl hydrogen bonds.
