The metals to ligand molar ratios of the complexes were found to be 1: 1. The complexes are 1: 2 electrolytes for Pb(II) and Zn(II) complexes and 1: 3 electrolytes for La(III) as shown by their molar conductivities (I >(m)) in DMSO at 10(-3) mol L-1. Due to the existence of free ions in these complexes, such complexes are electrically conductive. The configurations of La(III) and Zn(II) complexes were proposed to probably octahedral.eninfo:eu-repo/semantics/closedAccessArticle554583593Q4WOS:000277345800007Q22-s2.0-7795215244710.1134/S0036023610040157
