扩散法合成了Salen-镍(Ⅱ)单核配合物Ni(H2DS).CH3OH[H4DS=N,N'-二(3-羧基水杨醛)-(1R,2R)-环己二胺]。通过X-ray单晶衍射对配合物进行表征。配合物属单斜晶系,P2(1)/C空间群,晶胞参数:a=7.907(3),b=16.884(5),c=16.300(6),α=90°,β=103.562(6),γ=90°,分子式:C23H24N2NiO7,Mr=499.15,V=2115.2(12)3,Z=4,Dc=1.567 Mg/m3,R1=0.0562,wR2=0.1630[I>2σ(I)]。晶体由一个单核配合物Ni(H2DS)和一个没有配位的CH3OH分子组成。

The Salen-nickel （Ⅱ） complex Ni（H2DS）.CH3OH [H4DS = N,N＇（3-carboxylsalicylidene）-（1R,2R）- diaminocyclohexane] was synthesized by diffusion. The structure was characterized by single crystal X-ray diffraction. It crystallized in monoclinic system, P2（1）/C space group, with a=7.907（3） A, b=1 6.884（5） A, c=1 6.300（6） A, a=90°, β=103.562（6）, y= 90°, Molecular formula：C23H24N2NiO7 Mr =499.15, V=2115.2（12） A3, Z= 4, Dc 1.567 Mg/m^3, Ri=0.0562, wR2=0.1630[I〉2σ（I）]. The crystal included a mononuclear complex Ni（H2DS） and a non-coordinated CH3OH molecular.
