the stereochemistry of the actinide elements has recently undergone considerable development and a wide variety of coordination numbers and geometries have been observed. this structural versatility arises from the lack of strong crystal field effects for the 5f-electronic configurations as well as from the large ionic radii of these metal ions, which change markedly with oxidation number, or a...

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 ...

The present work describes the studies on the coordination behaviour of 4[N-(benzalidene) amino]antipyrine semicarbazone (BAAPS) (I), 4[N-(furfural)amino]antipyrine semicarbazone (FFAAPS) (II) and 4[N-(cinnamalidene)amino]antipyrine semicarbazone (CAAPS) (III) in presence of dimethyl sulfoxide (DMSO) or diphenyl sulfoxide (DPSO) towards Th4+ and UO22+ salts. All the complexes were isolate...

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 ...

Abstract The present study aims at the identification and investigation of fatty acid and amino acid profiles in male and female Liza aurata in the southern part of the Caspian Sea, in reproductive (autumn) and non-reproductive (spring) seasons. The results showed difference between the total fatty acids levels in the sexes. Analyses of fatty acids indicated a higher percentage of C16:0, C...
