Abstract:
A new iodiplumbate/organic hybrid constructed from asymmetric viologen and polyiodides, (PBPY-H-2)(2)[PbI4(I-3)(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 P2(1)/c with M-r = 1936.72, a = 11.622(2), b = 14.839(3), c = 13.372(2) angstrom, beta = 109.447(3)degrees, V = 2174.6(7) angstrom(3), Z = 2, D-c = 2.958 g/cm(3), F(000) = 1712, mu(MoKa) = 11.011 mm(-1), the final R = 0.0389 and wR = 0.0854 for 3866 observed reflections with I > 2 sigma(I). [PbI4(I-3)(2)](4-) mononuclear cluster of 1 features a seldom example of coordinated I-3(-) donors for the lead center. Intermolecular hydrogen bonds between [PbI4(I-3)(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.
