|Title:||Some lanthanide (III) nitrate complexes of N-(4' -benzoylidene-3'-methyl-1' -phenylpyrazol- 5' -one )isonicotinylhydrazine|
Sarojini, K R
|Abstract:||Nine new complexes of lanthanide (Ill) nitrates with N-(4' -benzoylidene-3' -methyl-1' - phenylpyrazol-S' -one) isonicotinylhydrazine (BMPIH) have been synthesised. All these complexes have the general formula [Ln(BMPIH)2(NO3)3] where Ln =La, Pr, Nd, Srn, Eu, Gd, Tb, Dy and Y. In these complexes BMPIH acts as a neutral bidentate ligand utilizing the azomethine nitrogen and the ring carbonyl oxygen as the donor atoms. The nitrate groups coordinate in a unidentate fashion and, hence. a coordination number of 7 is assigned to the central metal Ion.|
