Preparation of a series of cobalt (II) and nickel (II) complexes supported by tris(1-ethyl-4-isopropyl-imidazolyl-?N)phosphine (T1Et4iPrIP) have been performed. While structurally T1Et4iPrIP is similar to Tp- ligands, it differs in that it is neutral and is therefore a better mimic for enzymes containing 3-His metal binding site. Results indicate that T1Et4iPrIP can bind cobalt in both a tridentate and bidentate fashion while for nickel, only the tridentate mode is observed. Magnetic studies have also been performed to help derive structure-magnetic correlations.
