Synthesis of Catena-bis(μ-bromo)-( O -methyl- N -phenylthiocarbamate)-dicopper(I) and Its Reactivity towards PAr 3 (Ar = Ph, p -Tol)

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 2 -Br) 2 Cu}{μ 2 -MeOC(=S)N(H)Ph} 2 ] n   CP1 . Compound 1 was characterized by IR spectroscopy and an elemental analysis. The formation of a polymeric 1D ribbon built upon μ 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 3 (Ar = Ph, p -Tol), the polymer chain was broken to yield the mononuclear complexes [(Ar 3 P) 2 Cu{MeOC(=S)N(H)Ph}Br] C1 and C2 .
