摘要
The title mononuclear cobalt（Ⅱ） complex [Co（DENP）2（MeOH）2].2NO3 （DENP = 2-[2-（diethylamino）ethyliminomethyl]-4-nitrophenolate） was prepared and characterized by elemental analysis, 1R and single-crystal X-ray diffraction. The crystal belongs to the triclinic system, space group P1 with a = 8.297（1）, b = 11.075（2）, c = 11.134（2） ,A,α = 69.69（1）, β = 70.97（2）, γ = 84.02（2）°, Z = 1, V = 907.0（4） ,A^3, Dc= 1.424 g/cm^3, Mr = 777.66, λ（MoKα） = 0.71073 A,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-H...O, O-H...N and N-H...O hydrogen bonds, forming chains parallel to the b axis.
