Synthesis of Catena-bis

In order to investigate the coordination chemistry of O-alkyl N-aryl thiocarbamate ligands toward coinage metals, CuBr was reacted with one equivalent of MeOC(=S)N(H)Ph L in MeCN solution to afford the 1D-polymeric title compound [{Cu(μ[sub.2] -Br)[sub.2] Cu}{μ[sub.2] -MeOC(=S)N(H)Ph}[sub.2] ]nCP1. Compound 1 was characterized by IR spectroscopy and an elemental analysis. The formation of a polymeric 1D ribbon built upon μ[sub.2] -bridging bromido and thione ligands via the C=S bond was ascertained by a single-crystal X-ray diffraction study performed at 100 K. In the presence of PAr[sub.3] (Ar = Ph, p-Tol), the polymer chain was broken to yield the mononuclear complexes [(Ar[sub.3] P)[sub.2] Cu{MeOC(=S)N(H)Ph}Br] C1 and C2.
