摘      要：One new Ni（Ⅱ） complex [Ni（H2L）]Cl（H2O）3 based on one in-situ synthesized Schiff base ligand H3L （H3L = bis（benzyl-2-pyridylidene）-diaminoguanidine） was prepared and structurally characterized by single-crystal X-ray diffraction method. The complex crystallizes in the monoclinic system, space group C2/c with a = 27.944（7）, b = 7.7405（19）, c = 25.999（7） ,A, β = 115.545（2）°, V = 5074（2） A^3, Mr = 566.69, Z = 8, Dc = 1.484 g/cm^3, F（000） = 2352,μ（MoKα） = 0.912 mm^-1, R = 0.0594 and wR = 0.1477 for 5145 observed reflections （1 〉 2σ（I））. The complex exhibits one mononuclear structure in which the Ni（Ⅱ） atom adopts a [NiN4] pseudo-planar square geometry. Interestingly, along the b axis, each two neighboring [Ni（H2L）]^＋ units by an inverse center form pairs of molecules through the intermolecular benzene-pyridine π…π interactions.
