Reaction of o-C₆H₄(PPhH)(SH) (3) with Mn(CO)₅Br and Re(CO)₅Br in chloroform provided sulfido-bridged binuclear complexes {fac-[o-C₆H₄(PPhCl)(μ₂-S)]Mn(CO) ₃}₂ (4) and [o-C₆H₄(PPhH)(μ₂-S)](μ ₂-Br)Re₂(CO)₇ (5), respectively. Both complexes 4 and 5 were characterized by spectral and crystal structural analyses. The hydrogen atom of the secondary phosphine moiety (P-H) of 3 was replaced by a chlorine atom in dimanganese complex 4 to form P-Cl but was retained in rhenium complex 5. Methanolysis of 4 gave methoxyl-substituted product {fac-[o-C₆H₄(PPh(OCH₃))(μ ₂-S)]Mn(CO)₃}₂.
