Comparison between the chemical behaviors of different complex compounds formed by divalent transition metal ions with a heterocyclic ligand, leading to different structures

Abstract

The main purpose of the present paper is to identify the structures for the complexes formed by six divalent transitional metal ions (namely Ni(II), Pd(II), Pt(II), Zn(II), Cd(II) and Hg(II)) with the same heterocyclic ligand, that is able to change the coordination manner, consequently affecting the structure of the respective complex compound.
