Ethylene Thiourea

A number of Ni(II) complexes of thiourea, N-methylthiourea, N,N′-dimethylthiourea, N-naphthylthiourea, N,N′-diethylthiourea, and ethylene thiourea have been studied in acetone solution by proton magnetic resonance, magnetic susceptibility measurements, and conductivity measurements. In solution these complexes have tetrahedral, square planar, and octahedral geometries. In many cases equilibria between compounds with different geometries exist. Such equilibria have been studied as a function of temperature. The factors determining the relative stability of Ni(II) compounds with different geometries are discussed. In the present series of compounds it is concluded that the charge on the metal ion has the predominant influence in determining geometry. Some qualitative results on ligand exchange rates and mechanisms are also reported.
