4-(2-thiazolyl)-1-(2-hydroxybenzaldehyde)thiosemica1badone as a chelating ligand : Complexes with oxovanadium(IV) cobalt(II) nickel(II), copper(II), cadmium(II) and mercury(II)

Abstract

Complexes of the compositions VO(H2thbtsc)S04 Co(H2thbtsc)Cl2 M(H2thbtsc)2Ci2[M = Ni(II), Cu(II), Cd(II) and Hg(II)] and M(thbtsc).nH20 [M = VO(XV), Co(II), n=0; Ni(ll) and Cu(II), n = 2; H2thbtse = 4-(2-thiazolyl )-l-( 2-hydro xybenzaldehyde )thio seraicarb a zone] have been prepared and characterised by analytical data, electrical conductance, magnetic and spectroscopic studies. The bonding and stereochemistry of the complexes and chelating mode of the ligand are discussed. © 1989, Taylor & Francis Group, LLC. All rights reserved.
