Abstract
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.
