摘　　要：本文报道了一个新配合物—二（邻香草醛缩丙醇胺根）异硫氰酸根合锰（Ⅲ）的合成及其晶体结构。配合物属于单斜晶系，空间群为Ｐ２１／ｃ，晶胞参数为：ａ＝８５６５（１），ｂ＝２１８１４（２），ｃ＝１２７８７（２），β＝９２８０（１）°。锰为六配位，在两个邻香草醛缩丙醇胺Ｓｃｈｉｆ碱配体中，一个为三齿配体，另一个为双齿配体。ＮＣＳ－离子以Ｎ在轴向上与锰发生配位，由于ＪａｈｎＴｅｌｅｒ效应，其键长为２１９３Ａ。另外晶胞中存在着罕见的Ｈ……Ｓ－Ｃ≡Ｎ氢键。In this paper a new coordination compound, bis[N (3 hydroxypropyl) 3 methoxy salicyldi mino] thiocyanato manganese (Ⅲ)] , was synthesized and its crystal structure was determined The crystal data are as follows: crystal system, monoclinic; space group, P2 1 / c ; a =8 565(1), b=21 814(2), c=12 787(2) , β =92 80(1)° Manganese is six coordinated, and the coordination sphere is octahedral Between the two Schiff base ligands, N (3 hydroxypropyl) 3 methoxyl salicydimine, one acts as bidentate ligand, and the other acts as tridentate ligand NCS - ion coordinates to the central metal ion via the N atom in the axial direction The bond length of Mn N(NCS) is 2 194 , due to the Jahn Teller distortion There are H…S-C≡N bonds among the molecules in the crystal
