Synthesis and structural characterization of two new polynuclear metal thiosaccharinates: Hexakis(thiosaccharinato)hexasilver(I) and tetrakis(thiosaccharinato)tetracopper(I)

Polynuclear silver(I) and copper(I) thiosaccharinates are examined. The silver thiosaccharinate has a highly regular hexanuclear molecular structure, [Ag6(tsac)6] (tsac: thiosaccharinate anion), where the silver atoms are at the corners of an octahedral core slightly compressed along one of its three-fold axis, and the thionates act as bridges between three metals in a μ3-N,S (η2-S, η1-N) six-electron donor system. In contrast, the copper(I) thiosaccharinate has a highly distorted tetranuclear molecular structure, [Cu4(tsac)4(MeCN)2], where the metals show three different environments.
