Synthese And Structures Study Of Coordination Polymers Based On Triazole And Derived Ligands

The aim of this thesis is to synthesize new coordination polymers on the basis of1,2,4-triazole ligands and their derived ligands and different multicarboxylate ligands, to explore the synthetic conditions and rules for these compounds, analysis influence of organic ligands and metal ions on the formation of final structures, and to study the relationships between structures and properties for these new coordination polymers. In this thesis,25new coordination polymers were synthesized under the hrdrothermal condition, and structurally characterized by elemental analyses, IR, XRPD, TG and single crystal X-ray diffractions.1. Nine new coordination complexes have been synthesized on the basis of1,2,4-triazole ligand and different multicarboxylate ligands with d10metal ions under the hydrothermal condition with different structures. Complexes1and2are three-dimensional networks constructed by1,2,4-triazole ligand and Zn or Cd ions; complexes3-9are three dimension networks based on1,2,4-triazole and different multicarboxylate ligands with different structures. In addition, compound9is a three dimensional chiral network.[Zn2(TRZ)4(HTRZ)2]n(1)[Cd2(TRZ)3I]n(2){[Zn2(TRZ)(pBDC)1.5H2O]·(H2O)4}n(3){[Cd2(TRZ)(pBDC)1.5H2O]·(H2O)0.5}n(4){[Zn(TRZ)(mHBDC)H2O]·(H2O)4}n(5){[Zn5(TRZ)4(BTC)2H2O2]·(H2O)6}n(6){[Zn6(TRZ)6(HOBA)2(OBA)2]·(H2O)7}n(7){[Cd3(TRZ)2(OBA)2]·(H2O)0.5}n(8){Cd(TRZ)2(PZDC)0.5}n(9)2. Ten new coordination complexes have been synthesized on the basis of derivant of1,2,4-triazole ligand and different multicarboxylate ligands with Zn and Cd ions under the hydrothermal condition with different dimensional structures. Complexes17is one-dimensional chain structure; compound12and15are one-dimensional nanotube like structures; complexes13,14and18are two-dimensional layer structures and compounds11,16,19are three-dimensional networks. The structures of these complexes present that the1,2,4-triazole ligand are very helpful for the formation of coordination complexes with different dimensional structures, and the difference of organic ligands have important effective on the final structures.[Zn(L1)2(pBDC)·H2O]n(10)[Cd(L1)(pBDC)·3H2O]n(11) [Zn(L1)2(mBDC)·0.5H2O]n(12)[Cd(L1)(m B D C)·2H2O]n(13)[Zn(L1)2(BTC)·3.5H2O]n(14)[Cd(L1)2(BTC)·2H2O]n(15)[Zn2(L1)(PMA)·3H2O]n(16)[Zn(L2)2(pBDC)1(pBDC)0.5](17)[Zn(L2)2(mBDC)·3H2O]n(18)[Cd(L2)2(pBDC)(pBDC)0.5·3H2O]n(19)3.
