An unprecedented process involving normal and redox transmetallation reactions between Hg and Pt affording the unexpected K[Pt-2{CH2C(O)Me}(6)(mu-Cl)(3)] complex: the key role of X-ray powder diffraction in unravelling its nature and structure

摘要

Hg{CH2C(O) Me}(2)] reacts with K[PtCl3(CH2LCH2)] (2 : 1 molar ratio) to give K[Pt-2{CH2C(O) Me}(6)(mu- Cl)(3)] ( 1); the intermediate [Pt{CH2C(O) Me} Cl-2(CH2=CH2)](-) has been detected in solution and isolated as a Me4N+ sa the process occurs through successive normal and redox transmetallation reactions and an ab initio X-ray powder diffraction study of 1 has proven to be essential to establish its nature.
