摘　　要：The hydrothermal reaction of ZnO with benzene 1,4 dicarboxylic acid gave Zn·BDC·2H 2O (1) and Zn·BDC·H 2O (2) (BDC=benzene 1,4 dicarboxylate), respectively. Polymer 1 (C 4H 4O 3Zn 0.5 ) shows a one dimensional zigzag chain structure built up from the alternate connection of tetrahedral ZnO 4 and BDC units. Polymer 2 (C 4H 3O 2 5 Zn 0 5 ) possesses a three dimensional framework containing infinite zigzag Zn···Zn···Zn pseudochains generated by five coordinate zinc centers and a rectangular channel system including three groups of different straight channels along the [001], [010] and [60 1] directions. The two metal organic polymeric compounds exhibit strong photoluminescent emission bands at 402 nm ( λ ex =260 nm) (for 1) and at 344 nm and 385 nm ( λ ex =279 nm) (for 2) in the solid state at room temperature.The hydrothermal reaction of ZnO with benzene 1,4 dicarboxylic acid gave Zn·BDC·2H 2O (1) and Zn·BDC·H 2O (2) (BDC=benzene 1,4 dicarboxylate), respectively.
