摘要：
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 (FeMnI)-Mn-III, (FeMnII)-Mn-III and (MnMnII)-Mn-II core oxidation states for [Cl3M(mu-NC)Mn(CO)(dppm)(2)](z)(M = Fe, z = 0, 1; M = Mn, z = 0) respectively; (FeMnI)-Mn-III complexes show strong solvatochromism, consistent with low spin d(6) octahedral Mn-I to tetrahedral d(5) Fe-III charge transfer.
