observed reflections converged to R = 0.087. The structure comprises a distorted square planar Rh(I) environment where the coordination positions are taken by COD and the two nitrogen atoms of the bipm ligand. The six-membered RhNPCPNRh metallacycle has a distorted boat conformation. Synthesis and spectroscopic data of the pure complexes II and III are described. The formation of the complexes and
