A new organomercury(II) compound derived from both 3-ferrocenyl-2-crotonic acid and its decarboxylation product

摘要

A new Hg(II) complex [Hg(OOCCH=(CH3)CFcXCH=(CH3)CFc)] · MeOH (Fc = (η~5-C5H5)Fe(η~5-C5H4)) (1) was obtained by the reaction of Hg(OAc)2 with FcC(CH3)=CHCOONa in methanol solution. X-ray structural analysis reveals that the center Hg(II) ion is two-coordinated by the FcC(CH3)=CHCOO~- unit and the decarboxylation FcC(CH3)=CHC~- unit. This is the first example of Hg(II) monomer containing both ferr-ocenyl carboxylate and its decarboxylation product. Its thermal properties were investigated under N2.
