Abstract
The Co (II) complex, [Co (CNCHMe2) 3 {P (C6H4OMe-p) 3 }2) (ClO4) 2, is reported. Reaction data are consistent with this complex being an intermediate in reduction/ligand substitution reactions of Co (II)-organoisocyanide complexes with tertiary phosphines. Characterization data for this complex are consistent with trigonal bipyramidal coordination in solid and solution states.
