摘要: A tridentate ONN donor Schiff-base hydrazone ligand, H2L, was synthesized by the condensation of 2-amino-4-hydrazino-6-methyl pyrimidine with o-hydroxyacetophenone. The structure ligand elucidated IR and 1H NMR spectra which indicated presence three different coordinating groups, oxygen atom phenolic OH group, nitrogen azomethine, C=N, group one atoms heterocyclic ring. behaves either as a (N2O sites) neutral, mono- or di-basic bidentate (NO monobasic depending on pH reaction medium metal ion. mass spectrum showed molecular ion peak. Different types complexes, mononuclear such [(HL)M(OAc)]·xH2O (M = Cu Zn), [(HL)M(OAc)H2O]·xH2O Ni UO2), [(HL)Co(OH2)Cl]·2H2O, [(H2L)FeCl3]·3½H2O, [(L)FeCl(H2O)2]· 2¼H2O, [(HL)L'FeCl(H2O)]·H2O (L' 8-hydroxyquinoline, 8-HQ), [(HL)L'FeCl]Cl·xH2O 1,10-phenanthroline, p...
