Abstract

Complexation of a preformed complex [Hg(Tab)2](PF6)2 (1) with nicotinic acid in the presence of Et3N afforded a mononuclear complex [Hg(Tab)2(nico)]2(PF6)2 (2) (nico = nicotinate, Tab = 4-(trimethylammonio)benzenethiolate) which, upon subsequent treatment with one or three equiv. of CdCl2·2.5H2O, gave rise to an unprecedented heterometallic cage complex [Cd(H2O)6]@{Cd6Cl4(nico)12[Hg(Tab)2(μ-Cl)]2} (3) or a simple salt of [Hg(Tab)2][CdCl4] (4).
