A novel 2-D {[Cd-4(tpt)(2)(Cl)(4)(2,4-pdc)(2)]center dot 4H(2)O}(n) (1) has been synthesized from the hydrothermal reaction of 3,5,6-tris(2-pyridyl)-1,3,5-triazine (tpt), hydrated CdCl2, and 2,4-dicarboxylic acid (2,4-H(2)pdc). Compound 1 crystallizes in triclinic, P (1) over bar space group with alpha = 8.9434(5), b = 9.5486(7), c = 17.5772 (8) angstrom, a = 75.014 (5), beta = 83.778(5), gamma = 68.304(6)degrees, V = 1347.14(14) angstrom(3), C50H38Cd4Cl4N14O12, M-r = 1618.32, D-c = 1.990 g/cm(3), S = 0.95, mu(MoK alpha) = 1.83 mm(-1), F(000) = 788, Z = 1, R = 0.039 and wR = 0.080. The structure consists of tetranuclear [Cd-4(tpt)(2)(Cl)(4)](4+) cores as the secondary building unit, which is further connected by the ligand pdc(2-) to give a 2-D extended structure. Tpt entities are located on both sides of each 2-D framework and act as 'side arms' to form a corrugated layer and the adjacent layers are arranged in a tongue-and-groove interdigitating fashion. 1 was characterized by IR, TGA, PX1RD, and elemental analysis. The solid state luminescent properties were also investigated at room temperature.
