A new Cd(II) coordination polymer, namely, [Cd-2(Cl)(1,3-BDC)(1.5)(L)(2)]center dot 1.25H(2)O (1) (L = 2-(2-chloro-6-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,3-benzenedicarboxylate (1,3-BDC) was synthesized under hydrothermal conditions. The crystal of 1 belongs to orthorhombic, space group P bcn with a = 31.3116(19) angstrom, b = 13.5485(8) angstrom, c = = 22.9850(15) angstrom, alpha = 90 degrees, beta = 90 degrees, gamma = 90 degrees, C50H28.5Cd2Cl3F2N8O7.25, M-r = = 1226.46, V = 9750.8(10) angstrom(3), Z = 8, D-calc = 1.671 g cm(-3), S = 1.038, mu(MoK alpha) = = 1.106 mm(-1), F(000) = 4860, R = 0.0585 and wR = 0.1485. Compound 1 exhibits a 1D-ladder structure. Furthermore, neighboring 1D-ladders are joined together by pi center dot center dot center dot pi interactions to result in a 2D supramolecular layer. The thermal behavior of 1 was characterized. Furthermore, its luminescent properties were studied in the solid state at room temperature.
