A novel viologen（4,4＇bipyridinium）-based complex （CH3-4,4＇-H2bipy）（HgCl4） （1）,in which the CH3-4,4＇-H2bipy （MQ2＋） was generated in situ,has been synthesized via hydrothermal reaction and structurally cha...A novel viologen（4,4＇bipyridinium）-based complex （CH3-4,4＇-H2bipy）（HgCl4） （1）,in which the CH3-4,4＇-H2bipy （MQ2＋） was generated in situ,has been synthesized via hydrothermal reaction and structurally characterized. Complex 1 crystallizes in the space group P21/c of monoclinic system with four formula units in a cell：a = 8.1848（6）,b = 21.809（2）,c = 9.0285（6） ,β = 107.377（1）°,V = 1538.0（2） 3,C11H11Cl4HgN2,Mr = 513.61,Dc = 2.218 g/cm3,S = 1.009,μ（MoKα） = 10.685 mm-1,F（000） = 956,R = 0.0360 and wR = 0.0812. The crystal structure analysis reveals that the title complex features an isolated structure based on a CH3-4,4＇-H2bipy moiety and a mercury atom terminally bound by four chlorine atoms. Photoluminescence investigation reveals a strong emission in blue region,which may originate from π→π＊ charge-transfer interaction of the CH3-4,4＇-H2bipy moiety.展开更多
An unprecedented oxo-centered, trinuclear iron nicotinato cluster, [Fe30o （C6NO2Hs）6（H20）3][Fe（H30）2C16]＇12H20＂6Br （1）, has been prepared via hydrothermal reac- tions and structurally characterized by X-ray ...An unprecedented oxo-centered, trinuclear iron nicotinato cluster, [Fe30o （C6NO2Hs）6（H20）3][Fe（H30）2C16]＇12H20＂6Br （1）, has been prepared via hydrothermal reac- tions and structurally characterized by X-ray diffraction. Compound 1 crystallizes in the R-3c space group of rhombohedral system with a = 21.763（4）, c = 24.361（3） A, V = 9992（3） A3, C36H66Br6C16Fe4N6030, Mr = 1978.51, De. = 11973 g/cms, S = 1.006,/（MoKa） = 4.778 mm-1, F（000） = 5880, Z = 6, R = 0.0591 and wR = 0.1054. The title complex features an isolated structure, based on one discrete [Fe30（C6NO2H5）6（H20）3]7＋ cation, one [Fe（H30）2C16]- anion, twelve lattice water molecules and six isolated bromine anions. These isolated moieties are interconnected via hydrogen bonds to yield a three-dimensional （3-D） supramolecular network. Photoluminescent investigation reveals that the title complex exhibits an emission in the purple region. Theoretical study reveals that the emission is attributed to the metal to ligand charge-transfer （MLCT） interaction.展开更多
