Self-assembling copper(I) clusters involving electron-deficient, quadruply bridging thiolate ligands
Abstract
The structures of two new compounds containing the Cu12(µ4-S)6 Atlas-sphere cluster have been determined: (CuBr)13(SR)6·xH2O (x = ca. 1.5) and (CuCl)17(SR′)6 (SR = CH2CH2NH3, SR′ = CH2CH2NHMe2). The zwitterionic ligands are unique amongst simple thiolates in forming µ4 bridges between four metal ions. The formation of these materials from solutions which contain an excess of the thiolate is discussed.
