The peculiarities of the spatial structure of Cd(II), Hg(II), In(III), Tl(III), Sn(II) AND Pb(II) metallic salts complex compounds

Abstract

The geometrical parameters of complex compounds of Cd (II), Hg (II), In (III), Tl (III), Sn (II), Pb(II) metal salts with sulpher containing organic ligand were carried out using the MOPAC – 7.0 program by the guantum chemical PM3 method. It has been shown that the shortest M – S connection between a complex forming ion and a sulpher containing ligand forms in Hg (II) complexes, and the longest connection forms in Tl (III) complexes.
