Reactions and mechanisms of chloroplatinic acid hexahydrate with dimethyldi(4-N,N-dimethylaminophenyl)silane

► Complex salt [H(dma)]2(PtCl6)·0.5ace (2·0.5ace) was prepared unexpectedly. ► The crystal structure of 2·0.5ace shows the intramolecular neutralization effect. ► Proposed reaction mechanism shows the Si-C bond cleavage in common organic solvent.
