چکیده مقاله :
New coordination polymer of [HgLCl2]n (1) with HgCl2 and Schiff base bidentate ligand (4-methoxyphenyl) pyridine-2yl methyleneamine (L) was prepared and structurally characterized. In the 1D network structure of 1, the mecury (II) ion adopts an HgN2Cl3 distorted square pyramid geometry. In this complex, one of the chlorine acts as bridging ligand connecting two adjacent mercury(II) ions while, the L ligand is coordinated to mercury(II)ion in a cyclic-bidentate fashion forming an five-membered metallocyclic ring. Coordination compounds1 has been characterized by infrared spectroscopy, UV-visible spectroscopy, elemental analyses and single-crystal X-ray diffraction. The compound crystallizes in the monoclinic space group P 21/c with a = 9.3053(17), b = 7.1125(13), c = 20.708(4), and β = 80.208(4)°. The antibacterial activities of the complex, ligand and metal salt were tested against Gram-positive bacteria Staphylococcus aureus and Gramnegativebacteria Escherichia coli studied by disk diffusion method.
