Solvothermal reactions of Cd(OAc)2·2H2O with 3,3′-azodibenzoic acid (H2L) in N,N′-dimethylformamide (DMF) or DMF/MeOH at 100 °C or 120 °C gave rise to three cadmium(II) coordination polymers {[CdL(DMF)2]·0.5DMF}n (1), [CdL(DMF)(MeOH)]n (2) and {[Cd3L3(DMF) 4]·0.5DMF}n (3). Complexes 1-3 were characterized by elemental analysis, IR, powder X-ray diffraction and single-crystal X-ray diffraction. In 1-3, dinuclear [Cd2L4(DMF)4] (1) or [Cd2L4(DMF)2(MeOH)2] (2) unit and trinuclear [Cd3L6(DMF)4] (3) unit acts as a four-connecting node to link its equivalent ones via sharing L ligands to form 2D layers, which are further connected through the C-H?π (1) or hydrogen-bonding interactions (2-3) to afford 3D networks with the 4 1263 topology. The network of 1 allows other one to be penetrated for the formation of twofold interpenetrating pcu net. The formation of 1-3 provided an interesting insight into solvent and temperature effects on the construction of coordination polymers under solvothermal conditions. In addition, the photoluminescent properties of 1-3 in solid state at ambient temperature were also investigated.
