The title complex Ni （HCSP） 2·H2O[ H2 CSP-N-3-carboxylsalicylidene -1,2 -diaminopropane] was synthesized in methanol at room temperture. The structure was characterized by IR and single crystal X-ray diffraction, h crystallizes in monoclinic system, space group P2（ 1）/c, with a = 0.975 6（2） nm, b = 1.423 6（3） nm, c = 1.7403（4） nm, α=90°,β=98.951（3）°,γ=90°, Molecular formula is C22 H28 NiN4 O7, Mr = 519.19, V = 2. 3878（8） nm3, Z = 4, Dc = 1. 430 Mg/m^3, F （000） = 1 068, R1 = 0.071 9, wR2 = 0. 184 4, S =0.962. The crystal is constructed with mononuclear units, in which the nickel atoms are coordinated by two phenolic oxygen atoms and four imine nitrogen atoms.
