Abstract

First row transition metal (M = Mn–Ni) dichlorides react with cyanomanganese(I) carbonyl ligands to give novel paramagnetic bi- and poly-nuclear cyanide-bridged complexes, X-ray structural studies on which are consistent with FeIIIMnI, FeIIIMnII and MnIIMnII core oxidation states for [Cl3M(µ-NC)Mn(CO)(dppm)2]z (M = Fe, z = 0, 1; M = Mn, z = 0) respectively; FeIIIMnI complexes show strong solvatochromism, consistent with low spin d6 octahedral MnI to tetrahedral d5 FeIII charge transfer.
