Pillared-layer MOF Based on Template-directed Method: Synthesis, Structure and Proton Conduction Properties

By using Co(NH3)(6)(3+) as the template, a new complex HNU-38 was synthesized under hydrothermal reaction through the adoption of H3BTC and Cl- as the ligands (H3BTC = 1,3,5-benzenetricarboxylic acid). FIND-38 crystallized in the monoclinic system, P2(1)/1c space group with a = 9.9696(3), b = 17.0580(6), c = 16.5263(6) angstrom, beta = 100.400(2)degrees, Z = 4, V = 2764.31(16) angstrom(3), M-r = 883.63, D-c = 2.123 g/cm(3), F(000) = 1736, S = 0.920, R = 0.0358 and wR = 0.0838 (I > 2 sigma(I)). In HNU-38, the Cd2+ and BTC3- were linked together to form layers with CF serving as the pillar. It should be noted that (H2O)(n) chains were found in the channels and play a co-templating role along with the Co(NH3)(6)(3+) cations in HNU-38, and the proton conduction properties were investigated.
