| Abstract: | Trivalent lanthanide complexes of the type KML
2] whereM=La(III), Pr(III), Nd(III), Sm(III), Eu(III), Gd(III) and Dy(III) and H2
L=N-isonicotinamidosalicyladimine, have been prepared and characterised. The nephelauxetic ratio (β), covalency (δ) and bonding
parameter (b
2) of KNdL
2] have been calculated. Infrared spectral studies reveal that N-isonicotinamidosalicylaldimine acts as a dibasic tridentate
ligand. A coordination number six has been proposed for the lanthanide metal ions. |
