Copper(I) and silver(I) complexes of N-methyl-rhodanine and N-amino-rhodanine

Abstract

The following copper(I) and silver(I) complexes of N-methyl-rhodanine (MeRd, L) and N-amino-rhodanine (H 2NRd, L′) have been prepared and studied by infrared and conductometric methods: CuXL (X = Cl, Br, I), CuClO 4L 4, CuXL′ [X = Cl( 4 1HAc), I( 4 1DMF)], Cu 2Br 2L′ · 4 1HAc, Cu 2X 2L′ 2.55 ′> c41DMF (X = Cl, Br), CuClO 4L′ 2 · HAc, AgNO 3L, AgNO 3L′, AgClO 4L′ 2, AgClO 4L′ 2. The MeRd is coordinated through the thiocarbonyl sulphur atom and in most of its complexes through the ring-notrogen atom. The H 2NRd is coordinated through the amine nitrogen and the thiocarbonyl sulphur atoms. Most of the complexes have a tetrahedral coordination.
