| 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. |
