| 中文摘要 | Two new organically templated borates, [H(2)DAB][B(7)O(9)(OH)(5)](.)2H(2)O (1) and [H(2)DAB][B(7)O(10)(OH)(3)] (2), have been synthesized under mild conditions in the presence of DAB acting as structure-directing agent (DAB = 1,4-diaminobutane). The structures were determined by single crystal X-ray diffraction and further characterized by FTIR, elemental analysis, and thermogravimetric analysis. Both 1 and 2 crystallize in the same triclinic system, space group P (l) over bar (No. 2); 1: a = 8.238(4) angstrom, b = 8.348 (5) angstrom, c = 14.574(8) angstrom, a = 101.050(3)degrees, beta = 92.313(7)degrees, gamma = 112.694(5)degrees, V = 900.3(8) angstrom(3), Z = 2; 2: a = 8.8769(3) angstrom, b = 9.3204(2) angstrom, c = 10.2204(5) angstrom, alpha = 74.474(2)degrees, beta = 85.292(5)degrees, gamma = 72.730(2)degrees, V = 778.01(5) angstrom(3), Z = 2. The structure of 1 consists of [B(7)O(9)(OH)(5)](2-) groups, which represents the first example of organically templated heptaborate. The structure exhibits interesting hydrogen-bonded network formed by borate polyanion [B(14)O(20)(OH)(6)](4-), which can be regarded as being constructed from the dehydration of the FBBs in 1. The diprotonated organic amines are filled in the free space of the hydrogen-bonded network and interact with the inorganic framework by extensive hydrogen bonds. |
