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).
