摘要：

Addition of chloro- and amidoximes (RRC)-C-1=NOH (R/R-1 = Cl/Ph, Cl/C6H4-p-Me, Cl/C6H4-p-NO2, NH2/Ph) to the acetonitrile ligands in trans-[PtCl4(MeCN)(2)] proceeds much slower as compared to ketoximes with donor substituents R/R-1 [V.Yu. Kukushkin, T.B. Pakhomova, Yu.N. Kukushkin, R. Herrmann, G. Wagner, A.J.L. Pombeiro, Inorg. Chem. 37 (1998) 6511] and leads to the complexes with iminoacylated species [ligating (alkylideneaminooxy)imines] trans-[PtCl4 (NH=C(Me)ON=CRR1)(2)]. X-ray crystal structure determination of two iminoacylated compounds (R/R-1 = Cl/C6H4-p-Me, Cl/C6H4-p-NO2) disclosed their overall trans geometry with monodentate organic ligands in E-conformation and indicated =NH...N hydrogen bonding between the imino H atom and the oxime nitrogen.
