In this work, a new two-dimensional Cd(II) coordination polymer, [Cd-3(L)(2)(cis-1,4-chdc)(2)(trans-1,4-chdc)] (1, L = 11-fluoro-dipyrido [3,2-a:2',3'-c]phenazine and 1,4-H(2)chdc = 1,4-cyclohexanedicarboxylatic acid), has been prepared under hydrothermal conditions. It crystallizes in triclinic, space group P (1) over bar with a = 8.6951(8), b = 10.8362(9), c = 14.9445(13) angstrom, alpha = 76.443(2), beta = 81.8670(10), gamma = 82.0640(10)degrees, V = 1347.0(2) angstrom(3), Z = 1, C60H48Cd3F2N8O12, M-r = 1448.26, D-c = 1.785 g/cm(3), F(000) = 722, mu(MoKa) = 1.255 mm(-1), R = 0.0333 and wR = 0.0790. The 1,4-chdc(2-) carboxylates bridge the Cd(II) cations to form a tri-nuclear Cd(II) cluster, which are held together by the cis-1,4-chdc(2-) ligands to generate a double-stranded chain. Further, the trans-1,4-chdc(2-) ligands bridge adjacent double-stranded chains to yield an interesting two-dimensional network. The pi-pi interactions among L ligands of neighboring networks result in an interesting three-dimensional supramolecular architecture. In addition, the thermal behavior and luminescent property of 1 have been studied.
