摘 要: | 1 INTRODUCTION The significance of cobalt coordination com- pounds in biological systems is recognized1~3]. In many instances the cobalt coordination compounds of Schiff bases have been suggested as models to describe energy transfer in naturally occurring systems. In such cases the coordination sphere about the metal ion is believed to play an important role in determining the nature of the model system4, 5]. In order to investigate the structures of such complexes, we report herein t…

Abstract: | The title mononuclear cobalt(II) complex Co(DENP)2(MeOH)2](2NO3 (DENP = 2-2-(diethylamino)ethyliminomethyl]-4-nitrophenolate) was prepared and characterized by elemen- tal analysis, IR and single-crystal X-ray diffraction. The crystal belongs to the triclinic system, space group P with a = 8.297(1), b = 11.075(2), c = 11.134(2) , α = 69.69(1), β = 70.97(2), γ = 84.02(2)o, Z = 1, V = 907.0(4) 3, Dc = 1.424 g/cm3, Mr = 777.66, λ(MoKα) = 0.71073 , μ = 0.548 mm-1, F(000) = 409, R = 0.0628 and wR = 0.1734. The complex consists of a Co(DENP)2- (MeOH)2]2+ cation and two disordered nitrate anions. The Co atom, lying at the inversion centre, is six-coordinated by two DENP ligands and two MeOH molecules in an octahedral geometry. The molecules in the crystal are linked through intermolecular O-HO, O-HN and N-HO hydrogen bonds, forming chains parallel to the b axis. |
