Two complexes, one is binuclear Ni(II) complex 1, another is mononuclear Ni(II) complex 2 with the ligand TPA [TPA=tri(2- pyridylmethyl) amide], have been synthesized. Their structures have determined by single crystal X-ray diffraction method. The binuclear Ni(II) complex, C~3~6H~3~6N~8Ni~2Cl~2).11/6(ClO~4).1/6(OH).8/6(H~2O), is trigonal system, space group R-3, a=2.8425(4)nm, b=2.8425(4)nm, c=1.4385(5)nm, α=β=90.00ⅲ, γ=120.00ⅲ, Z=18, final R=0.078, Rw=0. 078. The crystal of mononuclear Ni(II) complex, C~2~0H~1~8N~6NiS~2 . 0. 5(H~2O) is triclinic system, space group, P1, a=0.9467(1)nm, b=1.5566 (3)nm, c=1.5913(3)nm, α=73.59(4)ⅲ, β=87.37(3)ⅲ, γ=76.27(2)ⅲ, Z=4, R=0.0784, Rw=0.238. The variable temperature magnetic susceptibility (4-300K) of complex 1 indicates there is a ferromagnetic intramolecular interaction (J=6.72cm^-^1) and weak antiferromagnetic intermolecular interaction (θ =-0.60cm^-^1).
