Two new indium phosphites, (C2N2H10)[In(OH)3(HPO3)] I and (C4N2H12)[In2(HPO3)3(H2PO3)2] II have been synthesized under mild hydrothermal conditions using ethylenediamine and piperazine as structure-directing agents, respectively and characterized by single-crystal X-ray diffraction, powder X-ray diffraction, IR spectroscopy, TGA, ICP-AES and elemental analyses. Compound I displays a one-dimensional ladder structure containing edge-sharing four-member rings. Compound II displays a complex three-dimensional open-framework containing multi-dimensional intersecting eight-membered ring channels. It is noted that compound II is the first organically templated indium phosphite with three-dimensional open-framework. Another striking feature of II is that it possesses a novel two-dimensional double sheet which is constructed by H2PO3 pseudo-pyramids and the one-dimensional ladders that are similar to those observed in I. Crystal data: I, H14C2N2O6PIn, M = 307.94, orthorhombic, space group P212121, a = 6.6483(6) Å, b = 9.7106(9) Å, c = 12.9537(12) Å, V = 836.28(13) Å3, Z = 4, and II, H19C4N2O15P5In2, M = 719.70, monoclinic, space group P21/c, a = 9.4610(2) Å, b = 9.4028(2) Å, c = 20.963(5) Å, β = 100.186(1), V = 1835.6(7) Å3, Z = 4.
