Reactivity of 1,1-DithioIato Ni(II) and Co(II) with Phenylthiourea, Chlorophenylthiourea and Bis(diphenylphosphinothioyl)methane

Abstract

Abstract The following mixed ligand complexes were synthesized and characterized: Co(Phdtcz)2(Phtu)2, Co(Phdtcz)2(Clphtu)2 , Co(Phdtcz)2(dtm), Ni(Et2dtc)2(dtm), Ni(Phdtc)2(dtm), Ni(p-Toluiddtc)2(dtm), Ni(α-naphdtc)2(dtm), and Ni(Phdtcz)(Et2dtc); where Phdtcz = phenyldithiocarbazate, Et2dtc = diethyldithiocarbamate, Phdtc = phenyldithiocarbamate, p-Toluiddtc = p-toluidinedithiocarbamate, α-naphdtc = α-naphthyldithiocarbamate, Phtu = phenylthiourea, Clphtu - chlorophenylthiourea, and dtm - bis(diphenylphosphinothioyl)-methane. Electronic and IR spectra, magnetic, conductivity and X-ray powder diffraction measurements were carried out. The Ni(II) and Co(II) complexes are suggested to be square planar and octahedral, respectively. The biological activity of the complexes was also tested.
