Synthesis, structure, and physicochemical characteristics of the cobalt(II) nitrate complex with α-(3,3-dimethyl-3,4-dihydroisoquinolyl-1)hydroxyiminoacetonitrile [Co(LH)(L)(NO3)]

The cobalt(II) nitrate complex with α-(3,3-dimethyl-3,4-dihydroisoquinolyl-1)hydroxyiminoacetonitrile [Co(LH)(L)(NO3)] (I) has been synthesized and studied by X-ray diffraction, IR, and electronic spectroscopy. One of the ligands is in the molecular form LH, and the other is the L- anion. The two independent ligands bidentately chelately coordinate the cobalt(II) atom via nitrogen atoms. The coordination polyhedron of the cobalt atom is a distorted octahedron. The NO 3 - group is bidentately chelately coordinated. The LH and L ligands are in the same E-s-cis- isomer form. Some data on the IR and electronic spectra of complex I are reported. © 2015 Pleiades Publishing, Ltd.
