[PtCl4(NH=C(Me)ON=C[C4Hs]C=NOH)2] (4) was isolated exclusively in cis configuration with the two metallaligand "arms" held together by intramolecular hydrogen bonding between the two peripheral OH groups, as it was proved by single-crystal X-ray diffractometry. The classic substitution products, e.g. [PtC12(N,N-dioximato)2] (12-15), are formed in the addition reaction as only byproducts in minor yield;
vic-dioximes 与有机腈铂 (IV) 配合物 trans-[PtCl4(RCN)2] 的反应 (R = Me, CH2Ph, Ph, vic-dioxime = 二甲基乙二肟;R = Me, vic-dioxime = cyclohexa-, cyclohepta - 和环辛二酮二肟)在相对温和的条件下快速进行,并提供二肟与腈碳的一端加成产物,即 [PtC4(NH=C(R)ON=[spacer]=NOH)2] (1 -6) (R = Me, CH2Ph, Ph, 间隔基 = C(Me)C-(Me) 用于二甲基乙二肟;R = Me, 间隔基 = C[C4H8]C, C[C5H10]C, C[C6H12]C 用于其他二肟),产生一种新型的金属配体。所有加成化合物均通过元素分析(C、H、N、C1、Pt)、FAB 质谱以及 IR 和 1H、13C[1H] 和 195Pt NMR 光谱进行表征。二甲基甲酰胺双溶剂化物
