Cyanomanganese-(I) and -(II) carbonyls as redox-active donor ligands: the synthesis of novel paramagnetic heterobinuclear complexes

The cyanomanganese complexes trans-[Mn(CN)(CO)(dppm)2]z(z= 0, 1+)(dppm = Ph2PCH2PPh2), cis-[Mn(CN)(CO)2L(L–L)], and trans-[Mn(CN)(CO)2L(L–L)]z(z= 0, 1+) have been used as ligands in the synthesis of redox-active heterobinuclear complexes such as [L(L–L)(CO)2Mn(µ-CN)Ru(CO)2(PPh3)(o-O2C6Cl4)]z(z= 0, 1+) and [(dppm)2(CO)Mn(µ-CN)RhCl(CO)2]z(z= 0, 1+).
