A novel mercury（H） 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, tH 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）, γ = 96.093（5）°, Z = 2, Dc = 1.817 ***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.

The syntheses and characterization of novel biferrocene trinuclear complexes of Schiff base ligand, S methyl N (ferrocenyl 1 methyl methylidene)dithiocarbazate [hereafter abbreviated as HL (1)], are described. The X ray diffraction studies have established the structures of PdL 2 (3) and CuL 2 (4). The geometry of Pd(Ⅱ) in (3) is close to a square plane and in the novel cis configuration the two ferrocene moieties are in cis configuration, while that of Cu(Ⅱ) in (4) is close to a tetrahedral configuration. The electrochemical measurements suggested that the square planar configuration of Ni(Ⅱ) and Pd(Ⅱ) moieties can effectively transmit the redox effects of the ferrocene moieties, while the tetrahedral configuration of the Cu(Ⅱ) complex can not transmit the redox effects. The degenerate four wave mixing (DFWM) measurements showed that the complexes exhibit obviously nonlinear optical (NLO) response. The magnitude of their third order NLO susceptibility can be explained by their structure and electrochemical properties.
