A novel mercury(Ⅱ) complex HgL2Br2 was prepared from HgBr2 and the organic ligand 2-(N-methyl-N-(4-((E)-2-(pyridine-4-yl)vinyl)phenyl)amino)ethanol (L).The ligand was synthesized and then characterized by FT-IR spectroscopy,1H NMR,mass spectrum and elemental analysis,while the single-crystal diffraction data of the complex were collected on a Siemens Smart CCD diffractometer.The complex crystallizes in triclinic space group Pi with a = 5.367(5),b =12.466(5),c = 23.945(5)(A),α = 90.812(5),β = 96.318(4),y = 96.093(5)°,Z = 2,Dc = 1.817 g·cm-3,μ= 7.395 mm-1,S = 0.825,and the final R = 0.0396.The Hg(Ⅱ) ion in the distorted tetrahedral mercury(Ⅱ) complex C32H36HgBr2N4O2 is coordinated by two N atoms from the two ligands together with two bromide ions.Solid-state emission of the ligand and its complex has been investigated at room temperature.
