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

ABSTRACT: 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. The two remaining coordination sites are occupied by two water mol-ecules. In addition, there are two uncoordinated water mol-ecules in the asymmetric unit. The crystal structure is stabilized by a network of O-H?O and O-H?N hydrogen-bonding inter-actions, forming a three-dimensional structure.

(2,2'-Bipyridine)bis-(3-carboxy-pyrazine-2-carboxyl-ato)copper(II) dihydrate.

Project description:The title six-coordinated distorted octa-hedral complex, [Cu(C(6)H(3)N(2)O(4))(2)(C(10)H(8)N(2))]·2H(2)O, consists of two 3-carboxy-pyrazine-2-carboxyl-ate anions and one 2,2'-bipyridine ligand.

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.

Bis(?-5-carboxyl-ato-1-carboxyl-ato-methyl-2-oxidopyridinium)-?O:O;?O:O-[diaqua-(phenan-throline-?N,N')manganese(II)] dihydrate.

Project description:The centrosymmetric binuclear title complex, [Mn(2)(C(8)H(5)NO(5))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)]·2H(2)O, was obtained by the reaction of manganese chloride with 5-carb-oxy-1-carboxy-methyl-2-oxidopyridinium and 1,10-phenanthroline. The Mn(II) atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, two O atoms from two 5-carboxyl-ato-1-carboxyl-atomethyl-2-oxidopyridinium ligands and two water mol-ecules, leading to a distorted octahedral MnN(2)O(4) environment. Inter-molecular O-H?O hydrogen bonds link neighbouring mol-ecules into a layer structure parallel to (001).
