摘 要: | The title mononuclear Schiff base nickel(Ⅱ) complex Ni(C11H14Br2N2O)2(H2O)2]·2NO3·2C2H3N was prepared and characterized by elemental analysis, IR spectrum, and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/n with a = 15.534(2), b = 7.647(1), c = 16.435(2) (A), β = 103.252(2)o, V = 1900.3(4) (A)3, Z = 2, Dc = 1.750 g/cm3, Mr = 1000.99, λ(MoKα) = 0.71073 (A), μ = 4.776 mm-1, F(000) = 996, the final R = 0.0368 and wR = 0.0724. A total of 3988 unique reflections were collected, of which 2764 with I>2σ(I) were observed. The complex consists of a mononuclear Ni(C11H14Br2N2O)2(H2O)2]2 cation, two nitrate anions and two acetonitrile molecules. The Ni atom, lying on the inversion centre, is six- coordinated by two Schiff bases and two water molecules to assume an octahedral coordination geometry. The molecules in the crystal are linked through intermolecular hydrogen bonds of N-H…O, N-H…Br, O-H…O, O-H…N and C-H…O to form layers.
