钪与1－苯基－3－甲基－4－苯甲酰吡唑啉酮－5配合物Sc（PMBP）＿3的合成及晶体结构

Synthesis and Crystal Srtucture of Sc(Ⅲ)Complex of 1-phenyl-3-Methyl-4-Benzoyl-Pyrazolone-5

用Ｘ射线衍射方法测定了所合成标题配合物的晶体结构。晶体属三斜晶系，Ｐ空间群。晶胞参数：ａ＝３．０９０（２）ｎｍ，ｂ＝１．２０３４（６）ｎｍ，ｃ＝１．２０２５（６）ｎｍ；ａ＝８６．６４（４１，β＝８１．１３（５）ｙ＝８１．１１（５）°；Ｚ＝４．配合物中钪（Ⅲ）配位多面体为八面体。

Thecomplex Sc(PMBP)3has been synthsized,where HPMBp=1-phenyl-3- methyl- 4-benzoyl-pyrazolone- 5.Its crystal structure has been determined with a four- circle X-ray diffractometer,The crystal is triclinic with space group P 1.The cell pa- rameters are as follows:a=3.090(2)nm,b=1.2034(6)nm,c=1.2025(6)nm;a=86.64(4),β=81.13(5),γ=81.11(5)°;V=4.362(4)nm￣3,Z=4.In the crvstal Sc(Ⅲ)ion isccordinated by six oxygen atoms from three PMBP molecules, so that the ccordinationnumber of Sc(Ⅲ)is six ,froming an octahedron。
