Complexation of 1,3-dimorpholinopropane with Hg(II) and Zn(II) salts: Synthese, crystal structures and antibacterial studies

Two Hg(II) (1) and Zn(II) (2) complexes with general formulation M(DMP)Cl2 where DMP=1,3-dimorpholinopropane were synthesized and structurally characterized by physicochemical methods and single crystal X-ray diffraction. An X-ray structural analysis shows that in both complexes Hg and Zn are coordinated by two nitrogen and two chlorine atoms in a form of distorted tetrahedron. The ligand and related complexes have antibacterial activity against three Gram-positive bacteria and also against three Gram-negative bacteria. The results revealed that in some cases the antibacterial activity of Hg(II) complex exceeded the one of sulfisoxazole used as standard.
