The synthesis and properties of some nitroimidazole complexes of platinum and palladium starting from the MCl42- salts are described. Both 5-NO2-imidazole and metronidazole give cis-[MCl2L2] complexes whereas trans-[MCl2L2] is obtained for 2-NO2-imidazole and misonidazole. The crystal structure of trans-dichlorobis(misonidazole)platinum(II) was determined by three-dimensional X-ray methods. The compound
描述了从MCl 4 2-盐开始的一些铂和钯的硝基咪唑配合物的合成和性质。5-NO 2-咪唑和甲硝唑均产生顺式-[MCl 2 L 2 ]络合物,而对于2-NO 2-咪唑和咪唑则获得反式-[MCl 2 L 2 ] 。反式二氯双(咪唑)铂(II)的晶体结构通过三维X射线方法测定。在空间群P2 1中结晶的化合物/ c在离散的单体单元中,a = 11.303(5),b = 13.002(5),c = 8.125(3)Å,B = 91.39(3)°,Z = 2,观察和计算的密度分别为1.83和1.859分别。对于142个变量,最终的全矩阵最小二乘法细化得到R 1 = 0.037和R 2 = 0.045的值。该络合物是正方形平面,Pt-Cl和Pt-N的距离分别为2.294(3)和2.016(9)Å。咪唑基环的平均平面相对于PtCl 2 L 2扭曲56°正方形平面和Cl-Pt-N角分别为89.4(3)和90
