Abstract

La (III), Y(III) complexes wit11 diglycol aldehyde his-arginine (H2DAAR) and tetraglycol aldehyde bislysine (H2TALY) Schiff bases were synthesized. Thcy were characterized and formulated as La (H2DAAR) (NO3)3. 6H20 and Y (H2TALY) (NO3)3. 5H20 separately by elemental analyses. The obtained complexes were investigated in detail by high resolution solid state (HRSS)13C NMR using cross polarization, magic angle spinning (CPMAS). and total suppression of sidebands (TOSS) techniques. The results are supported by the liquid state 2D-’H-13C COSY NMR spectra. Some new information about the splitting peaks of13C for -CH = N- group and alkene carbon bands, etc. in HRSS13C NMR spectra are given.
