N,N'-Dicyclohexylthiourea and N,N'-Diphenylthiourea Complexes of Cobalt(II)

The N,N'-dicyclohexylthiourea (DCTU) and N,N'-diphenylthiourea (DPTU) complexes of Co(II) have been investigated. In organic solvents four-coordinated tetrahedral (or pseudo-tetrahedral) species are formed. Evidence is presented to indicate that both ligands undergo a structural change in...
