摘　　要：用Ｎｄ（ＮＯ３）３·６Ｈ２Ｏ、Ｉｍ（Ｃ３Ｈ４Ｎ２）、Ｐｈｅｎ（Ｃ１２Ｈ８Ｎ２）和Ｃｕ（ＮＯ３）２·３Ｈ２Ｏ为原料，两步反应合成了标题化合物．该化合物晶体属Ｐ１空间群，晶胞参数ａ＝１．０１２６（２）ｎｍ，ｂ＝１．１７９２（２）ｎｍ，ｃ＝１．３９８５ｎｍ，α＝１１１．３２（３）°，β＝９３．１７（３）°，γ＝９０．３３（３）°，Ｚ＝１，Ｒ＝０．０４３．测定了化合物的ＵＶ－Ｖｉｓ－ＮＩＲ及ＩＲ光谱和变温磁化率，发现标题化合物在低温下具有反铁磁性质．The crystal of [Nd(ONO 2) 6][Cu(Im)(phen) 2] 2(OH)·4H 2O was synthesized and its structure of its single crystal was determined by X ray diffraction. The crystal is triclinic system, space group P1 with a = 1 012 6(2) nm, b = 1 179 2(2) nm, c = 1 398 5 nm, α=111 32(3)°, β=93 17(3)°, γ=90 33(3), V = 1 552 6(5) nm 3, Z=1 , D c=1 700 g/cm 3, F (000) =801, R =0 043, R w=0 070. UV Vis NIR, IR and magnetic susceptibility were determined and the related properties of the complex were discussed. It is found that the title complex possesses the behavior of anti ferromagnetic material at low temperature.
