| In this work, thirteen new coordination polymers, which have never been reported,namely,[Cd（L）（H2O）]（1）,[Cd（L）2Na2] H2O （2）,[Cd（L）（phen）]（3）,[Cd（L）（phen）]2H2O（4）,[Cd2（L）2（biim-2）] H2O （5）,[Cd（L）（biim-4）]2H2O （6）,[Co（L）（biim-4）] H2O （7）,[Cd（L）（btp）]（8）,[Cd（L）（btb）]（9）,[Cd（HL）（bth）0.5（H2O）] H2O （10）,[Co（HL）（btb）0.5] H2O（11）,[Cd（L）（btbp）1.5]4H2O （12）, and [Ni（L）（bty） H2O]3H2O （13）, where phen=1,10-phenathroline, biim-2=1,2-bis（imidazol-1′-yl）ethane, biim-4=1,1′-（1,4-butanediyl）bis（imidazole）, btp=1,3-bis（1,2,4-triazol-1-yl）propane, btb=1,4-bis（1,2,4-triazol-1-yl）butane, bth=1,6-bis（1,2,4-triazol-1-yl）hexane, btbp=4,4′-bis（1,2,4-triazol-1-ylmethyl）biphenyl, bty=1,4-bis（tridazol-1-ylmethyl）-benzene, and H2L=（3-carboxyl-phenyl）-（4-（2-carboxyl-phenyl）-benzyl） ether, have been synthesized and characterized bysingle-crystal X-ray diffraction. In order to investigate the influence of organic anions andN-donor ligands on the structures of the compexes, we have synthesized compounds1-13.Compounds3-5and10-11display1D chains structure, compounds1-2,6-8and12show2D layers and compounds9and13possess3D framworks. In1, the2D layer isfurther stabilized by hydrogen-bonds interaction between the coordinated water moleculesand adjacent carboxylate oxygen atoms. Compound2shows a2D double layer with36·46·53topology. Compounds3and4exhibit similar1D double chains, which are further extendedinto2D supramolecular sheets and3D supramolecular frameworks through π-π interactionsbetween pyridyl rings and phenyl rings, respectively. Compound5furnishes a1D doublechain, which is further extended into a2D supramolecular layer via two kinds of π-πinteractions. Compounds6and7are isostructural, and display the same2D undulatedsheets with44·62topology. Compound8possesses a simple2D sheet structure. Compound9displays a3D （3,4）-connected frameworks with （4·102）（4·103·122） topology. Compounds10and11possess similar1D infinite chains, which are further linked via π-π interactions togenerate2D supramolecular layers. Compound12possesses a2D double layer, which arefurther extended into a3D supramolecular architecture through hydrogen-bondinginteractions. Compound13shows a3D uninodal6-connected framework with44·611topology. The structural and topological differences of the thirteen compounds indicate thatthe L anion and N-donor ligands play important roles in the formation of the finalframework structures. In addition, the thermal behaviors of compounds and luminescent properties of1-6,8-10and12have also been investigated in detail. |
