چکیده
The title mononuclear complex, [Ni(C(7)H(3)NO(4))(C(9)H(10)N(2))(3)], shows a central Ni(II) atom which is coordinated by two carboxyl-ate O atoms and the N atom from a pyridine-2,6-dicarboxyl-ate ligand and by three N atoms from different 5,6-dimethyl-1H--benzimidazole ligands in a distorted octa-hedral geometry. The crystal structure shows intermolecular N-H⋯O hydrogen bonds.

The title complex, [Cu(C(7)H(3)NO(4))(C(7)H(6)N(2))(H(2)O)]·0.75H(2)O, consists of discrete monomeric units. The Cu(II) atom is coordinated by two carboxyl-ate O atoms and the N atom from a dipicolinate unit and by an N atom from a benzimidazole ligand. The distorted square-pyramidal geometry is completed by a longer axial bond to the O atom of a water mol-ecule. The mol-ecular structure and pa...
