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.
