摘　　要：Three different dimensionalNi（II） coordination polymers, [Ni（3-pna）（HIP）（H2O）3]-H20（1）, [Ni（3-pna）- （1,3,5-HBTC）]（2） and [Ni2（H2O）（3-pna）2（1,4-CHDC）2]4（3）（3-pna=3-pyridylnicotinamide, H2HIP=5-hydroxyisoph- thalic acid, 1,3,5-H3BTC=l,3,5-benzenetricarboxylic acid, 1,4-H2CHDC=l,4-cyclohexanedicarboxylic acid）, were synthesized under hydrothermal conditions and characterized by means of infrared spectra（IR）, thermal gravimetric （TG） analyses, powder X-ray diffraction（PXRD） and single-crystal X-ray diffraction. Complex 1 has a structure of 1D single-stranded chain, which is further stretched by hydrogen-bond interactions to form a 2D supramolecular sheet. Complex 2 shows a 2D network, which is stretched to 3D supramolecular frameworks through hydrogen-bond interactions. Complex 3 reveals a 3D skeleton with a （3,3,6,6）-connected {3·72} {32·4 } {33·42·5·73·85·9 } {33·45·52·72·82·9} topology. The effects of different polycarboxylates on the ultimate architectures of the complexes 1--3 were dis- cussed. Furthermore, the fluorescent and photocatalytic properties of the title complexes were also investigated.Three different dimensionalNi（II） coordination polymers, [Ni（3-pna）（HIP）（H2O）3]-H20（1）, [Ni（3-pna）- （1,3,5-HBTC）]（2） and [Ni2（H2O）（3-pna）2（1,4-CHDC）2]4（3）（3-pna=3-pyridylnicotinamide, H2HIP=5-hydroxyisoph- thalic acid, 1,3,5-H3BTC=l,3,5-benzenetricarboxylic acid, 1,4-H2CHDC=l,4-cyclohexanedicarboxylic acid）, were synthesized under hydrothermal conditions and characterized by means of infrared spectra（IR）, thermal gravimetric （TG） analyses, powder X-ray diffraction（PXRD） and single-crystal X-ray diffraction.
