| Nowadays,the coordination polymers based on tripodal polycarboxylic acid ligand s have become a heated topic of coordination chemistry,which was due to their pote ntial applications in molecular recognition,magnetism,optical sensors,catalysis.By hy drothermal method,twenty complexes were synthesized based on the 3,5-bis（2-carboxy-phenoxy）-benzoic acid（H3BCPB）,and were characterized by single-crystal X-ray diffr action analysis,IR spectroscopy,elemental analysis,powder X-ray diffraction and ther mogravimetric analysis.At the same time,the complexes 1 and 2 have been determin ed by fluorescence spectrum,the magnetic properties of complexes 1,2,6,9,10,11 were investigated.The famulas of 120 are as follows: {[Cu3（BCPB）（HBCPB）（H2BCPB）（H2O）]·（CH3OH）（H2O）}n（1）{[Cd（HBCPB）（1,4-bib）1.5]·4H2O}n（2）[Zn2（BCPB）（OH）（H2O）] n（3）{[Zn2（BCPB）（OH）（H2O）2]·（CH3OH）}n（4）[Mn（HBCPB）（4,4-bibp）2（H2O）]n（5）[Cu（HBCPB）]n（6）{[Cu1.5（BCPB）（1,3-bibm）1.5]·（DMF）}n（7）{[Cu（HBCPB）（1,2-bibm）]·（H2O）}n（8）[M3（BCPB）2（4,4’-biby）3·（H2O）2]n（910）[M=Co（9）,Mn（10）] {[M3（BCPB）2（BI）2]·2H2O}n（1112）[M=Co（11）,Zn（12）] {[La（BCPB）（H2O）3]·H2O }n（13）{[La2（BCPB）2（H2O）2]·2H2O }n（14）[M（BCPB）（H2O）（DMF）]n（1516）[M=Eu（15）,Nd（16）] [M（BCPB）（H2O）2]n（1720）[M=Eu（17）,Nd（18）,Ce（19）,La（20）]Complex 1 is a（3,3,5,6）-connected 2D network structure,the 2D network packed into a three-dimensional supramolecular structure through hydrogen–bonding interactions.Polymer 2 is a 4-connected 3D dia framework.Complexes 3 and 4 are one-dimensional chain.5 is a zero dimensional structure.Complex 6 exhibits a（3,6）-connected 3D network structure Complex 7 is a 2D network structure.8 is a zero dimensional cage structure.9 and 10 are（3,4,6）-connected 3D network structure.11 and 12 are（3,6）-connected 2D network structure.13 is double nuclear two-dimensional structure.14 is multinuclear two-dimensional structure 15 and 16 are 3D porose structure.17 20 are（4,8）-connected 2D network structure. |
