Abstract

Synthesis and characterisation of cyano-bridged complexes of the form [(η-C₅R₄Me)L(ON)Mn(μ-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.
