[Ni(3)(η2-NO3)]NO3·CH3CN (5c·CH3CN), and [Ni(4)(η2-NO3)]NO3·CH3OH (5d·CH3OH). With NiCl2·6H2O, the complexes [Ni(1)Cl(H2O)]Cl·H2O (6a), [Ni(2)(μ-Cl)2Ni(2)]Cl2·2CH3OH (6b·2CH3OH), [Ni(3)Cl(H2O)]Cl (6c), and [Ni(4)(H2O)2]Cl2·H2O (6d·H2O) are obtained. The molecular structures of complexes 5a−d and 6b−d have been determined by X-ray diffraction analysis and they are compared with the molecular structure
