Recently, metal carboxylates coordination polymers(MCCP) have gained considerable attention due to their attractive structures and promising applications for catalysis, gas storage, magnetic materials, and optoelectronics. In this dissertation, we describe the syntheses, and structures of a series of novel MCCPs obtained under hydrothermal condition by using metal centers as nodes and PCPA, (predominant ligand) and pyridine derivatives(secondary ligand) as building blocks. The studied works are concluded in the following:First, 8 novel metal carboxylates coordination polymers and 3 supramoleculars formed by H-bonding andπ–πStacking weak interactions.have been designed and synthesized. X-ray single crystal diffractometer technology was employed to determine their structures: [Zn2(PCPA)2(IN)2]n 1 [Co(PCPA)(IN)]n 2 [Ln(PCPA)3(glycol)]n, [ Ln = La(3); Nd(4); Gd(5)] [Eu(PCPA)3(H2O)]n 6 [Co(PCPA)2(4,4'-bpy)]n 7 [Cu(PCPA)2(4,4'-bpy)]n 8 [Ag(PCPA)(PCPAH)(4,4'-bpy)·H2O]n 9 [Ag(HBTC)]n·[Ag(4,4'-bpy)]n 10 [Cu(H2BTC)(2,2'-bpy)] 11Among these compounds, the compounds 1and 2 are first constructed from mixed rigid and flexible carboxylate ligands, the most intriguing structural feature is that each complex exhibits both infinite helical Zn(μ2-carboxylate) or Co(μ3-carboxylates) chain units with 21 helices and zigzag M2(IN)2(M= Zinc and Cobalt) chain units by reason of two different carboxylate ligands coordinating to metal centers; Compounds 3, 4, and 5, an isomorphous series of three new lanthanide coordination polymers, form a 1D chain structure as it is with compound 6; Hydrothermal reaction of the...
