Self assembly of isostructural copper(I)-silver(I) butterfly clusters with 2-mercaptothiazoline; syntheses and structures of (PPh3)2Cu4(C3H4NS2)4, [(C5H5N)Cu4(C3H4NS2)4]n, (PPh3)2Ag4(C3H4NS2)4 and (PPh3)2Ag2Cu2(C3H4NS2)4
Abstract
The crystal structures of tetranuclear butterfly clusters of CuI, AgI and the mixed metal AgI2CuI2 compound as obtained by reaction of the metal acetates with 2-mercaptothiazoline, and subsequent treatment of the insoluble polymeric clusters with organic bases are reported.
