The Hg atom in the title complex, [HgCl2(C12H13N3)], adopts a square-pyramidal geometry, being ligated by three N atoms of the tridentate bis­(2-pyridylmeth­yl)amine ligand and two Cl atoms, with one of the latter occupying the apical position. Disorder is noted in the amine portion of the ligand and this was modelled over two sites, with the major component having a site-occupancy factor of 0.794 (14).

Luminescent organic and metal coordination compounds have attracted considerable attention for their potential applications in electroluminescent displays.1 Among coordination compounds, chelate d 10 metal complexes are of great interest due to their high thermal stability and low cost as well as their good photoluminescent and electroluminescent properties. ) complexes with 2-[4-(dimethylamino)styryl] pyridine (dmasp) were prepared and their structural and luminescent properties were investigated. The dmasp ligand was of interest as it had an electron push-pull system, thereby stabilizing the π* levels and, in them, ILCT transitions could arise readily through a conjugated π system, which is also important to ILCT photoluminescent materials as well as the second-order nonlinear optical (NLO) materials. 6 Experimental Synthesis of Zn(dmasp)2Cl2 (1).To a stirred solution of 2-[4-(dimethylamino)styryl]prydine (449 mg, 2.0 mmol) in methanol (15 mL) was added with a solution of ZnCl2 (272 mg, 2.0 mmol) in methanol (5 mL). The reaction mixture was stirred for 12 hr at room temperature. After filtering, the yellow precipitate was collected. Light yellow crystals of 1 were obtained by slow evaporation in a dichloromethane solution. as an internal reference. The absorption (UV-Vis) and photoluminescence (PL) spectra were measured by a Jasco V-570 UV-Vis spectrophotometer and a Hitachi F-4500 fluorescence spectrophotometer, respectively, from 200 to 800 nm. Cyclic voltammetry (CV) experiments were performed on a Bioanalytical Systems CV-50W voltammetric analyzer in a 0.1 M solution of tetrabutylammonium tetrafluoroborate (Bu4NBF4). The Pt disk electrode, Ag/AgNO3 (0.1 M) electrode and Pt electrode were used as the working, reference and counter electrodes, respectively, at a scan rate of 100 mV/s, and ferrocene was used as a reference. Thermal analyses were carried out on a Metler Toledo TGA/DTA 815 analyzer under a nitrogen atmosphere at a heating rate of 10 o C/min. Crystallography. X-ray intensity data were collected at room temperature on a Bruker SMART APEX-II CCD diffractometer using graphite monochromated Mo Kα radiation (λ = 0.71073 Å). Structure was solved by applying the direct method using a SHELXS-97 and refined by a full-matrix least-squares calculation on F 2 using SHELXL-97. All non-hydrogen atoms were refined anisotropically. All hydrogen atoms were placed in ideal positions and were riding on their respective carbon atoms (Biso = 1.2 Beq and 1.5 Beq). Crystal data for 1: C30H32Cl2 N4Zn, Mw = 584.87, Monoclinic, P21/n, a = 14.108 (2)

This Study is about art make-up designs applying formative Images of Marc Chagall focusing on practical training cases. The art makeup designs express aesthetical and emotional aspects of human mind. And the art make-up designs are in need of drawing skills and aesthetic sense. All the art make-up works were done by distortion, modifications and exagerations. The unique colors and the shapes of Marc Chagall’s art works were expresses in body torso through brush techniques. From this practical training cases, I expect that Marc Chagall’s painting skills could be applicable to the art make-up works. Finally, Six art make-up designs were created by six college students in Daejeon. The making process of art make-up designs were recorded every weeks by the students. Art make-up designs production method works with colors and geometric patterns inspired by flat art techniques hand-painting techniques. The results of this practical training cases contained different art make-up techniques and colors of Chagall's work. Formative characteristecs of Marc Chagall were applied to an expression method. New six art make-up designs were developed and the ides, types and expression method of art make-up were examined. In the future, we expect unique and beautiful high quality of art-make up designs.
