ResumoAddition of chloro- and amidoximes RR1C=NOH (R/R1=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/R1 [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/R1=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.
