چکیده
|
Lanthanide(iii) chloro complexes of 4[n-(4’-hydroxy-3’-methoxybenzalidene) amino] antipyrine semicarbazone (hmbaaps) (i) and 4[n-(3’,4’,5’-trimethoxybenzalidene) amino] antipyrine semicarbazone (tmbaaps) (ii) with the general composition lncl3.2l (ln = la, pr, nd, sm, gd, tb, dy or ho; l = hmbaaps or tmbaaps) are reported. all the complexes were synthesized in ethanolic medium and refluxed the reaction mixture (1:2.2, m:l ratio). the yield percentage ranging from 78 – 82%. the complexes are non-ionic in nature. the infrared spectral studies reveal that both of the semicarbazones are tridentate (n,n,o) ligands. magnetic spectral and thermal properties of the complexes have also been investigated. a coordination number nine is tentatively suggested in these complexes.
