[Hg3(SCH2CH2S)4]2– and {[Hg2(SCH2CH2S)3]2–}n: examples of trinuclear and quasi-isolated binuclear polymeric mercury thiolate anions
Abstract
On varying the reaction conditions, of HgCl2 with ethane-1,2-dithiolate and Ph4PBr in methanol yields either [Ph4P]2[Hg3(SCH2CH2S)4] containing isolated trinuclear anions or [Ph4P]2[Hg2(SCH2CH2S)3] with polymeric anions composed of quasi-isolated binuclear subunits; both mercury thiolates may reflect characteristic structural features of biologically active species.
