• New thiourea derivatives, 3-diphenylphosphinothioyl-1 -phenylthiourea (PTTU-A), 3-diphenylphosphinothioyl-1,1-diethyl thiourea (PTTU-B), and 3-diphenylphosphinothioyl-1,1-dimethylthiourea (PTTU-C) were found to behave as bidentate ligands with transition metal ions such as Ni(II), Pd(II), Co(II), and Cu(II) to give a series of novel metal chelates. The structures of these complexes are discussed on the basis of magnetic susceptibilities, infrared spectra, electronic spectra, powder X-ray diffraction patterns and elemental analyses. Tentative assignments of two metal-sulfur stretching vibrations in the far infrared spectra were made for Ni-PTTU and Pd-PTTU, which have square-planar configurations. However, the structures of the Cu-PTTU complexes could not be determined by these methods because of the instability of the complexes. They were confirmed by electronic and ESR spectroscopies.
