| Salen-type ligands are a kind of very important compounds, which has long been a research hotspot on coordination chemistry. Because these ligands have a N2O2 tetradentate coordinate environment, thus capable of forming a lot of kinds of stable metal complexes having different structures and properties. Among these Salen-type transition metal complexes, some can serve as catalyst of organic chemical reactions, some also can be used as optical materials. Salamo ligands are added two oxygen atoms on the basis of Salen-type ligands. As Salamo-type ligands have two larger electronegativity oxygen atoms, which make the C=N bond become more stable and not easy to hydrolysis and exchange reaction. So study on Salamo-type ligands are very meaningful.In this thesis,the 4,4’-dihydroxy-2,2’-[(ethylenedioxy)bis(nitrilomethylidyne)]diphenol H4L1 is obtained by the reaction of the 2,5-dihydroxyacetophenone with 1,2- bis(aminooxy) ethane in a 2:1, Then, 4,4’-dinitro- 2,2’- [1,2-ethylene-dioxy bis(nitril omethylidyne)]diphenol H2L2 is obtained by the reaction of the 5-nitrosalicylicaldehyde with 1,2-bis(aminooxy)ethane in a 2:1. Complexes were characterizated by using elemental analysis, solubility experiments, IR, UV absorption spectroscop ies, fluorescence properties and other analytical testing methods.Complexes 1, 2, 3, 4, 5 and 6 are obtained by the reaction of the 4,4’-dinitro-2,2’-[1,2-ethylene-dioxybis(nitrilomethylidyne)]diphenol H2L2 with Ni(OAc)2·4H2O and Co(OAc) 2·4H2O in a 1:1. By using of X-ray single crystal diffraction analysis to determine their composition and spatial configuration.Complexes 1: Empirical formula C46H56Cl6Co3N8O24, Formula weight of 1494.48, Crystal system, triclinic, space group P-1, crystal cell parameters: a = 11.1193(12) ?, b = 11.7721(9) ?, c = 13.8091(11) ?, β = 69.437(9)o, Z = 1, V = 1581.6(2) ?3, R1 = 0.0491, w R2 = 0.1282;Complexes 2: Empirical formula C42H46Co3N8O22, Formula weight of 1191.66, Crystal system, monoclinic, space group P2(1)/c, crystal cell parameters: a = 10.9254(6) ?, b = 15.1722(5) ?, c = 17.6784(9) ?, β = 99.992(5)o,Z = 2, V=2886.0(2) ?3, R1 = 0.0666, wR2 = 0.1953;Complexes 3: Empirical formula C44H50Co3N8O22, Formula weight of 1219.71, Crystal system, monoclinic, space group P2(1)/c, crystal cell parameters: a = 10.850(4) ?, b = 15.993(3) ?, c = 17.724(5) ?, β = 102.41(3)o, Z = 2, V = 3003.7(15) ?3, R1 = 0.1109, wR2 = 0.3465;Complexes 4: Empirical formula C38H38N8Ni3O22, Formula weight of 1134.89, Crystal system, triclinic, space group P-1, crystal cell parameters: a = 9.8878(6) ?, b = 10.7482(5) ?,c = 13.4889(6) ?, β = 69.603(5)o, Z = 1, V = 1263.44(11) ?3, R1 = 0.0419, w R2 = 0.1126;Complexes 5: Empirical formula C42H46N8Ni3O22, Formula weight of 1191.00, Crystal system,monoclinic, space group P2(1)/c, crystal cell parameters: a = 10.7265(5) ?, b = 14.8589(5) ?, c = 17.5199(11) ?, β = 99.911(5)o, Z = 2, V = 2750.7(2) ?3, R1 = 0.0579, w R2= 0.1610;Complexes 6: Empirical formula C36H34N8Ni3O22,Formula weight of 1106.84, Crystal system,monoclinic, space group C(2)/c, crystal cell parameters: a = 23.508(5) ?, b = 11.4156(18) ?, c = 23.490(5) ?, β = 112.10(2)o, Z = 4, V = 5840.5(19) ?3, R1 = 0.0630, w R2= 0.1553;... |
