Diaqua-bis-(hydrogen tartrato)cobalt(II) dihydrate.

ABSTRACT: The title complex, [Co(C(4)H(5)O(6))(2)(H(2)O)(2)]·2H(2)O, contains a Co(II) ion, two single deprotonated tartrate anions, two coordinated water mol-ecules and two lattice water mol-ecules. The coordination geometry of the Co(II) ion is a distorted octa-hedron with two O atoms from two coordinated water mol-ecules occupying cis positions in the equatorial plane and four O atoms from two hydrogen tartrate ions occupying the remaining positions. In the crystal, inter-molecular O-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

Diaqua-bis-(5-methyl-pyrazine-2-carboxyl-ato-?N,O)cobalt(II) dihydrate.

Project description:In the title complex, [Co(C(6)H(5)N(2)O(2))(2)(H(2)O)(2)]·2H(2)O, the coordination geometry of the Co(2+) cation is distorted octa-hedral, with two N atoms and two O atoms from two 5-methyl-pyrazine-2-carboxyl-ate ligands in the equatorial plane.

Diaqua-bis(tetra-zolo[1,5-a]pyridine-8-carboxyl-ato-?N,O)cobalt(II) dihydrate.

Project description:In the title compound, [Co(C(6)H(3)N(4)O(2))(2)(H(2)O)(2)]·2H(2)O, the Co(II) atom is located on an inversion center in a slightly distorted octa-hedral environment formed by the O atoms of two water mol-ecules, and the N and O atoms of the chelating tetra-zolo[1,5-a]pyridine-8-carboxyl-ate anions. Hydrogen bonds of the O-H?O and O-H?N types result in a three-dimensional supra-molecular network.

Diaqua-bis-(4-meth-oxy-benzoato-?O)bis-(nicotinamide-?N)cobalt(II) dihydrate.

Project description:In the mononuclear title compound, [Co(C(8)H(7)O(3))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)]·2H(2)O, the Co(II) ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 4-meth-oxy-benzoate anion, one nicotinamide (NA) ligand and one coordinated and one uncoordinated water mol-ecule. All ligands act in a monodentate mode. The four O atoms in the equatorial plane around the Co(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two pyridine N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 6.47?(7)°, while the pyridine and benzene rings are oriented at a dihedral angle of 72.80?(4)°. An O-H?O hydrogen bond links the uncoordinated water mol-ecule to one of the carboxyl-ate groups. In the crystal structure, inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

Diaqua-bis-(5-methyl-1,2-oxazole-3-car-box-yl-ato-?N,O)cobalt(II) dihydrate.

Project description:In the title compound, [Co(C(5)H(4)NO(3))(2)(H(2)O)(2)]·2H(2)O, the coordination polyhedron around the six-coordinate Co(II) ion is formed by two equatorial 5-methyl-isoxazole-3-carboxyl-ate ligands in an N,O(3)-bidentate fashion through the isoxazole N atom and a carboxyl-ate O atom, and by two axial water ligands. The asymmetric unit consists of half of the complex and one water mol-ecule (the full comlex being completed by application of inversion). In the crystal, the water mol-ecules participate in the formation of an intricate three-dimensional network of hydrogen bonds involving the coordinated water mol-ecule and the carboxyl-ate groups.

Diaqua-bis(2,2'-biimidazole)cobalt(II) dichloride.

Project description:There are independent cations and four chloride anions in the crystal structure of the title complex, [Co(C(6)H(6)N(4))(2)(H(2)O)(2)]Cl(2). In each cation, the Co(II) cation is coordinated by four N atoms from two biimidazole and two O atoms of two water mol-ecules; one Co atom is at a position of site symmetry m, the other at a position of site symmetry 2/m. All Cl(-) ions and water mol-ecules are also located on the mirror plane. Each structural unit is connected through O-H?Cl and N-H?Cl inter-molecular hydrogen bonds, forming a three-dimensional supramolecular structure.

Diaqua-bis-(dimethyl sulfoxide-?O)bis(saccharinato-?N)cobalt(II).

Project description:The title complex, [Co(C(7)H(4)NO(3)S)(2)(C(2)H(6)OS)(2)(H(2)O)(2)], contains a Co(2+) cation in an octa-hedral coordination environment. The metal atom is surrounded by two different neutral ligands, namely dimethyl-sulfoxide (DMSO) and water, each coordinating through the O atom. The anionic saccharinate (sac; 1,1,3-trioxo-2,3-dihydro-1?(6),2-benzothia-zol-2-ide) ligand coordinates through the N atom. Each of the three similar ligand pairs is in a trans configuration with respect to each other. The Co atom lies on a crystallographic center of symmetry and the octa-hedral geometry is not significantly distorted. A short O-H?O hydrogen bond is present between a water H atom and the ketone O atom; two longer hydrogen bonds (intra- and inter-molecular) are also present between a water H and a sulfonic O atom, forming a supramolecular assembly through head-to-tail aggregation between adjacent complexes.

Diaqua-bis[2-(benzyl-oxy)acetato]cobalt(II).

Project description:In the mononuclear title complex, [Co(C(9)H(9)O(3))(2)(H(2)O)(2)], each Co(II) atom is located on an inversion center and is hexa-coordinated by four O atoms from two benzyl-oxyacetate ligands [Co-O bond lengths = 2.0487 (9) and 2.1090 (9) Å] and two water mol-ecules [Co-O bond length = 2.0873 (9) Å] in a distorted octa-hedral geometry. In the crystal structure, inter-molecular hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance between phenyl rings = 3.692 (2) Å] link the mol-ecules into a supra-molecular structure.
