A new Cd(II) coordination polymer, namely, [Cd2(Cl)(1,3-BDC)1.5(L)2]?1.25H2O (1) (L = 2-(2-chloro-6-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,3-BDC = 1,3-benzenedicarboxylate), has been synthesized under hydrothermal condition. The crystal of 1 belongs to orthorhombic, space group P bcn with a = 31.3116(19) ?, b = 13.5485(8) ?, c = 22.9850(15) ?, ? = 90?, ? = 90?, ? = 90?, C50H28.5Cd2Cl3F2N8O7.25, Mr = 1226.46, V = 9750.8(10) ?3, Z = 8, Dc = 1.671 g/cm3, S = 1.038, ?(MoK?) = 1.106 mm-1, F(000) = 4860, R = 0.0585 and wR = 0.1485. Compound 1 shows a 1D ladder structure. Further, neighboring 1D ladders are joined together by ??? interactions to result in a 2D supramolecular layer. The thermal behavior of 1 has been characterized. In addition, its luminescent property has been studied in solid state at room temperature. nema
