Synthesis, X-ray spectral, and magnetochemical study of copper complexes based on tridentate azomethines of 3-allylsalicylaldehyde
摘要:
Tridentate azomethine ligands (H2L) based on 3-allylsalicylaldehyde and o-aminophenol, o-aminothiophenol, or 2-ethylamino-5-nitroaniline were synthesized and identified by IR and H-1 NMR spectroscopies. The structure of complexes (Ia-Ic) was studied by magnetochemistry and EXAFS spectroscopy. Complexes Ia and Ib (X = O, S) are binuclear and exhibit antiferromagnetic exchange interaction: 2J = -36.5 and -950 cm(-1), respectively. Complex Ic (X = NC2H5) is mononuclear (mu(eff) = 1.75 mu(B) at 275 K and does not change as temperature decreases).

of additives of copper azomethine complexes of different structure on the character of polycondensation and physicomechanical properties of the obtained metal-containing epoxy polymers was studied. It was shown by the DSC method that the thermal stability of the starting CuII azomethine complexes depended on their structure and nature of polar functional groups. The physicomechanical properties of
