title: Control over directional metal-metal charge transfer in cyanide-bridged dimanganese complexes: effects of mu-CN linkage isomerism and ancillary ligand set.
abstract: Synthesis and characterisation of cyano-bridged complexes of the form [(eta-C5R4Me)L(ON)Mn(mu-XY)Mn(CO)2-L'(dppm)]z (X,Y = C,N; z = 1-3) shows that systematic variation of the orientation of the CN bridge and the nature and geometric arrangement of the ancillary ligands affords control of the direction and energy of metal-metal charge transfer in the mixed valence dications.
