摘      要：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.
