Abstract
The title complex has been prepared using (4-fluoro-phenyl)-pyridin-2-ylmethylene-amine bidentate Schiff base ligand (L) and HgCl2. The Hg(II) center in the title compound, [HgCl2(C12H9FN2)], is covalently bonded to three Cl atoms and two N atoms of the diimine ligand. Mercury ion mononuclear fragment that forms a polymeric structure due to bridging chloride ligands is in a distorted trigonal-bipyramidal coordination environment formed by the bis-chelating N-heterocyclic ligand, two bridging Cl ligands and one terminal Cl ligand. One of the bridging Hg–Cl bonds is significantly longer than the other. In the crystal, weak C–H⋯Cl hydrogen bonds are observed in addition to π–π stacking interactions. It crystallizes in the orthorhombic space group P212121 with a = 7.2248(3) Å, b = 8.7713(3) Å, c = 20.0217(7) Å, α = 90.00°, β = 90.00°, γ = 90.00°, V = 1268.79(8) Å3, R1 = 0.023 and wR2 = 0.062 (I > 2σ(I)]. The antibacterial activities of the complex, ligand and metal salt were tested against Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria Escherichia coli studied by disk diffusion method.
