Abstract:

A new iodiplumbate/organic hybrid constructed from asymmetric viologen and polyiodides, (PBPY-H2)2[PbI4(I3)2] (1, PBPY = N-(propionate)-4,4-bipyridinium), has been synthesized via solvothermal reaction and structurally determined by X-ray diffraction method. Compound 1 crystallizes in monoclinic system, space group P21/c with Mr = 1936.72, a = 11.622(2), b = 14.839(3), c = 13.372(2) , β = 109.447(3), V = 2174.6(7)3, Z = 2, Dc = 2.958 g/cm3, F(000) = 1712, μ(MoKα) = 11.011 mm-1, the final R = 0.0389 and wR = 0.0854 for 3866 observed reflections with I > 2δ(I). [PbI4(I3)2]4- mononuclear cluster of 1 features a seldom example of coordinated I3 - donors for the lead center. Intermolecular hydrogen bonds between [PbI4(I3)2]4- clusters and (PBPY-H)2 4+ dimmers contribute to the formation of a 2-D layer. Its absorption spectrum was investigated, and lower energy band gap of 1.42 eV was explained by DFT calculation. Interestingly, 1 exhibits photocatalytic activity for the degradation of rhodamine B.
