Preparation and Characterization of Mercury (II) Complexes Containing 5-(Aryl) Azo-8-Quinolinol Ligands

Abstract

5-(Aryl) azo-8-quinolinol (LH = L H-L H) forms mercury(II) complexes of the type (L)₂Hg similar to the well known transition metal arylazo-8-quinolinolates but 5-( o -carboxyphenyl) azo-8-quinolinol (L⁶ HH') forms two types viz., the quinolinates (L⁶H') ₂Hg and the binuclear type (L⁶HgCl)HgCl. The quinolinates (L)₂Hg and (L⁶ H')₂Hg are tetrahedral while the mercury atom in (L⁶ HgCl)HgCl is a three-coordinated neutral species. These complexes were characterized by elemental analyses, conductance and IR data.
