title: Synthesis and structural characterization of four new organically-directed bismuth sulfates.
abstract: Four new organically-directed bismuth sulfates, (C(2)N(2)H(10))(3)[Bi(2)(SO(4))(6)(H(2)O)(2)] x 4 H(2)O (I), (C(5)N(2)H(14))[Bi(SO(4))(2)(HSO(4))(H(2)O)] x H(2)O (II), (C(4)N(3)H(16))[Bi(SO(4))(3)(H(2)O)] (III) and (C(6)N(4)H(22))[Bi(2)(SO(4))(5)(H(2)O)(2)] x 4 H(2)O (IV) 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. I and II both exhibit similar infinite courrgated anionic layers with 8-membered ring windows, III shows a new 1D ladder-like chain containing 4-membered rings, while IV 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.
