摘要：
Two new coordination polymers, {[Pb(mu(2)-H2TFMIDC)(2)-(mu(2)-H2O)]center dot.H2O}(n) (H3TFMIDC = 2-(trifluoromethyl)-4,5-imidazole dicarboxylic acid, 1) and [Ba(mu(2)-H2TFMIDC)(mu(4)-H2TFMIDC)(H2O)](n) (2), were constructed under hydrothermal/solvothermal conditions. Compound 1 is an achiral 3D framework based on irregular helical chains and displays a 6-connected pcu network topology. Compound 2 exhibits a 3D chiral framework based on homochiral 1D helical chains with a (4,8)-connected network topology. The luminescence properties of compounds 1-2 were also investigated.
