Synthesis and structural characterization of four new organically-directed bismuth sulfates

Four new organically-directed bismuth sulfates, (C(2)N(2)H(10))(3)Bi(2)(SO(4))(6)(H(2)O)(2)].4H(2)O (), (C(5)N(2)H(14))Bi(SO(4))(2)(HSO(4))(H(2)O)].H(2)O (), (C(4)N(3)H(16))Bi(SO(4))(3)(H(2)O)] () and (C(6)N(4)H(22))Bi(2)(SO(4))(5)(H(2)O)(2)].4H(2)O () have been synthesized and structurally characterized by single-crystal X-ray diffraction analysis. Four compounds were constructed from strictly alternating BiO(n) and SO(4) polyhedra. and both exhibit similar infinite courrgated anionic layers with 8-membered ring windows, shows a new 1D ladder-like chain containing 4-membered rings, while possesses a new flat layer with 12-membered ring windows. The diverse linking fashions of the five-connected Bi nodes and the mono-, bi- or tri-connected S nodes form unique Bi-S-Bi topologies. Their fluorescent properties are also reported.
