Reaction of o-C6H4(PPhH)(SH) (3) with Mn(CO)(5)Br and Re(CO)(5)Br in, chloroform provided sulfido-bridged binuclear complexes {fac-[o-C6H4(PPhCl)(mu(2)-S)]Mn(CO)(3)}(2) (4) and [o-C6H4(PPhH)(mu(2)-S)](mu(2)-Br)Re-2(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-CI but was retained in rhenium complex 5. Methanolysis of 4 gave methoxyl-substituted product {fac-[o-C6H4(PPh(OCH3))(mu(2)-S)]Mn(CO)(3)}(2).
