A new luminescent dinuclear cluster complex [Cd2(pzc)2(AmTAZ)(H2O)4(NO3)]·NO3 (Hpzc = pyrazine-2-carboxylic acid, AmTAZ = 3-amino-4H-1,2,4-triazole) has been prepared by the assembly of CdII with pyrazine-2,3-dicarboxylic acid and 3-amino-1H-1,2,4-triazole-5-car-boxylic acid ligands under hydrothermal conditions, in which in situ decarboxylation of H2pzdc and HAmTZC ligands simultaneously occurred, and H2pzdc was transformed into Hpzc while HAmTZC into AmTAZ. The crystal structure is of triclinic, space group P1 with a = 7.096(2), b = 11.140(4), c = 14.887(5), α = 92.641(4), β = 91.348(6), γ = 96.058(6)°, V = 1168.5(7)3, C12H18Cd2N10O14, Mr = 751.16, Z = 2, Dc = 2.126 g/cm3, F(000) = 730, μ = 1.910 mm-1, R = 0.0320 and wR = 0.0998 for 4549 observed reflections (I > 2σ(I)). The dinuclear cluster of 1 is extended into a 3D supramolecular architecture through intermolecular hydrogen bonding interactions. Complex 1 exhibits strong blue photoluminescence at room temperature.
