Description
Two new organically templated borates, [H3N(C6H10)NH3][B4O5(OH)4] (1) and [H3N(C6H10)NH3][B5O8(OH)] (2) have been synthesized in the presence of trans-1,4-diaminocyclohexane acting as a structure-directing agent under mild solvothermal conditions. The structures were determined by single crystal X-ray diffraction and further characterized by FTIR, elemental analysis and thermogravimetric analysis. Compound 1 crystallizes in the monoclinic system, space group C2/c (No. 15), a=9.1325(3)A, b=11.4869(3)A, c=12.2756(5)A, β=105.258(6)o, V=1242.37(7)A3, Z=4. The structure contains supramolecular hydrogen-bonded network formed by isolated [B4O5(OH)4]2- polyanions. 2 is monoclinic, space group P2(1)/n (No. 14), a=6.5176(2)A, b=16.8861(5)A, c=11.1522(7)A, β=91.897(6)o, V=1226.70(9)A3, Z=4. The structure consists of layers of 3,9-membered boron rings constructed from pentaborate anion groups [B5O8(OH)]2-. The adjacent borate layers are further linked with each other by hydrogen bond to form a 3D supramolecular network. It is the first example of layered borates templated by an organic amine
