摘要
合成了1-苯基-3-甲基-4-苯甲酰基-5-吡唑啉酮(HPMBP)缩DL-苯丙氨酸乙酯合Ni(Ⅱ)配合物,用X-射线衍射方法测定了其晶体结构,其分子式为C55H82N6NiO11,单斜晶系,空间群C2/c,α=2.9220(9)nm,b=1.3622(4)nm,c=2.1387(6)nm,α=90°,β=129.745(4)°,γ=90°,V=6.545(3)nm^3,Z=4,Dc=1.212Mg·m^-3,MoKαλA=0.071073nm,μ=0.358mm^-1,F(000)=2544.采用扫描方式,收集1.81°~25.00°范围内的独立衍射点15800个,其中I≥2σ者8488个,最终偏离因子R1=0.0593,wR2=0.1335.晶体中镍离子与4个O原子和2个N原子形成六配位的变形八面体结构,镍离子位于八面体结构的中心,配位的N和O原子位于八面体结构的6个顶点.
A nickel(Ⅱ ) complex with the ligand derived from 1-phenyl-3-methyl-4-benzoyl-5-pyrazoylone(HPMBP) and DL-phenylalanine ethyl ester was synthesized and characterized by IR, UV spectra and elemental analysis. The crystal structure of the complex was determined by X-ray diffraction method. The formula was C55H82N6NiO11 belonged to monoclinic and space groupC2/c,α=2.9220(9)nm,b=1.3622(4)nm,c=2.1387(6)nm,α=90°,β=129.745(4)°,γ=90°,V=6.545(3)nm^3,Z=4,Dc=1.212Mg·m^-3,MoKαλA=0.071073nm,μ=0.358mm^-1,F(000)=254 4;R1=0.0593,wR2=0.1335 5. The crystal structure indicated that the Ni complex coordinated with 4 nitrogen atoms and two oxygen atoms to form a distorted octahedral structure, in which the Ni ion lied on an inversion center and the oxygen and nitrogen atoms on the six tops.
