چکیده
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. The acid H atom of the ligand is distributed over two O atoms. In the crystal, a three-dimensional network is formed through O-H⋯O and N-H⋯O hydrogen bonds between the cations and anions.

The title complex, (NH(4))(2)[Co(C(3)H(3)O(4))(2)(H(2)O)(2)]·2H(2)O, features a six-coordinate Co atom located on a center of symmetry. The octa-hedral O(6) coordination geometry is defined by two bidentate malonate ligands and two water mol-ecules, with the latter in a trans configuration. The mol-ecules are linked through O-H⋯O and N-H⋯O hydrogen-bonding inter-actions, forming a three-dimensi...

In the title compound, (C(6)H(10)N(2))[Co(C(7)H(3)NO(4))(2)]·5H(2)O, the Co(II) ion is six-coordinated in an N(2)O(4) environment by two pyridine-2,6-dicarboxyl-ate (pydc) ligands, having a distorted octa-hedral geometry. The crystal packing is stabilized by inter-molecular N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonds. There are also π-π inter-actions between the pyridine rings of the pydc ligand...

In the title compound, (CH(6)N(3))(2)[Co(C(3)H(2)O(4))(2)(H(2)O)(2)], the anions lie on crystallographic centres of inversion. The crystal structure adopts a layered structure, stabilized by an extensive network of N-H⋯O and O-H⋯O hydrogen bonds. One H atom of the guanidinium cation does not participate in any strong hydrogen bonds.

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 ...
