Yttrium(III), lanthanium(III) and zirconium(IV) complexes of some bidentate schiff bases derived from hetero aromatic amines and salicylaldehyde

Abstract

Y(III), La(III), and Zr(IV) complexes with some heteroaromatic Schiff bases derived from salicylaldehyde and heteroaromatic amines, viz 2-amino-pyridine, -a m i n o -4 -p h e n y l t h i a z o l e and -a m i n o -5 -p h e n y l -1 , 3 , 4 -t h i a d i a z o l ehave been prepared, The s t r u c t~r e s o f the complexes have been investigated b y elemental analysis, the spectrophotometric molar ratio and continuous variation methods as well as infrared spectra. It is found that the complexes obtained are characterized by high coordination number.
