Some Complexes of Cobalt(II), Nickel(II), Nickel(II) Copper(II) and Zinc(II) with Disubstituted Thiourea

Abstract

Some new mononuclear and heterodinuclear complexes of the

type ML₂ and [ZnL₂·M'L₂] [where M = Co(II), Ni(II), Cu(II) and

Zn(II); M' = Co(II), Ni(II) and Cu(II) and HL = N-(2-thiophenol)

N-phenylthiourea (MPT) and N-(2-thiophenol)-N-ethylthiourea

(MET)] have been synthesized. Their tentative structures have been

assigned on the bases of elemental analysis, molar conductance

measurements, room temperature magnetic measurements, infrared

and electronic spectral data. The ligands act as monobasic bidentates

giving tetracoordinated species.
