Synthesis of Catena-bis(& mu;-bromo)-(O-methyl-N-phenylthiocarbamate)-dicopper(I) and Its Reactivity towards PAr3 (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(& mu;(2)-Br)(2)Cu}{& mu;(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 & mu;(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 PAr3 (Ar = Ph, p-Tol), the polymer chain was broken to yield the mononuclear complexes [(Ar3P)(2)Cu{MeOC(=S)N(H)Ph}Br] C1 and C2.
