The hexaaqua complex of a 3d transition metal, [M(H2O)6]SO4, has an effective magnetic moment corresponding to 5 unpaired electrons. Reaction of this hexaaqua complex with excess KCN gave K4[M(CN)6] which has an effective magnetic moment of 1 unpaired electrons. Deduce the identity of the metal, M, and explain your reasoning.
