The Synthesis, Crystal Structure And Properties Of Terpyridine Complexes And Cryptand Complexes

In this paper, the following research contents are reported:1.According to the literature, the 4’-phenyl-2,2’:6’,2"-terpyridine ligand (L) was synthesized via 2-acetyl pyridine and benzaldehyde, and two complexes were synthesized via (L) and four metal salts.Firstly, with the raw materials of NiCl2·6H2O,2,6-naphthalene acid sodium and ligand (L), complexes [Ni(2,6-C12H6O4)L]n (1) which contained bridging structure was synthesized by hydrothermal synthesis method. Secondly, with the raw materials of CUSO4·5H2O, terephthalic acid disodium and ligand (L), complexes [Cu2(μ2-O2SO2)(μ2-1,4-O2C2O2C6H4)L2]n·7H2O·DMF (2) which contained water chain structure was synthesized by hydrothermal synthesis method.The structures of complexes were determined and analysed by X-ray single crystal diffraction.The results showed that complexes (1) was six-coordinated with octahedral geometry and coordination polymer with MOF; and the complexes (2) was five coordinated with square pyramidal configuration and coordination polymer with MOF.2.With the raw materials of (L) and Cu(p-SO3PhCH3)2·MeOH, Cu(OCO-Ph)2·MeOH, Cu(m-OCOC6H4OH)2·0.5H2O, Cu(p-OCOC6H4OH)2·H2O, four terpyridine-copper (Ⅱ) complexes [Cu(p-SO3C6H4CH3)L(H2O)2](p-SO3C6H4 CH3) (1), [Cu(OCOPh)2L] (2), [Cu(w-OCOC6H4OH)2L]·MeOH (3), [Cu(p-O COC6H4OH)2L]·2H2O (4) were synthesized respectively. Their structures were determined and analysed by X-ray single crystal diffraction, IR and TG-DTA. The results showed that all those complexes were single-core six coordinated with octahedral geometry, and the centralions Cu (Ⅱ) were contained in the environment of octahedron configuration.3.The cryptand 1,4,7,10,13,16,21,24-octaazabicyclo [8.8.8] hexacos ane (L1), cryptand 4,7,13,16,21,24-six nitrilethyl 1,4,7,10,13,16,21,24-octaazabicyclo [8.8.8] hexacosane (L2) and cryptand 4,7,13,16,21,24-six carboxyethyl 1,4,7,10,13,16,21,24-octaazabicyclo [8.8.8] hexacosane (L3) were synthesized by oxalaldehyde and tris(2-aminoethyl) amine according to the literature methods. And a lot of complexes were synthesized by L1, L2, L3 and the following salts:Cd(p-CH3PhSO3)2, Cd(CH3CO2)2, Zn(m-CO2PhOH)2, Zn(CO2Ph)2, Zn(p-CH3PhSO3)2, Zn(CH3CO2)2, Ni(p-SO3PhCH3)2, NiCl2.6H2O, Ni(CH3CO2)2·4H2O, PdCl2, Sm(NO3)3·6 H2O, Eu(NO3)3·6H2O.
