摘　　要：La(Ⅲ) , Y(Ⅲ) complexes with diglycol aldehyde bis-arginine (H2DAAR) and tetraglycol aldehyde bis-lysine (H2TALY) Schiff bases were synthesized. They were characterized and formulated as La( H2DAAR) (NO3)3 ?6H2Oand Y (H2TALY)(NO3)3 ·5H2Oseparately 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-1 H-13 C COSY NMR spectra. Some new information about the splitting peaks of 13C for -CH=N- group and alkene carbon bands, etc. in HRSS 13C NMR spectra are given.La（Ⅲ）, Y（Ⅲ） complexes with diglycol aldehyde bis-arginine （H₂DAAR） and tetraglycol aldehyde bislysine （H₂TALY） Schiff bases were synthesized. They were characterized and formulated as La（H₂DAAR） （NO₃）₃·6H₂O and Y （H₂TALY）（NO₃）₃·5H₂O 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-¹H-¹³C COSY NMR spectra. Some new information about the splitting peaks of ¹³C for—CH=N—group and alkene carbon bands, etc. in HRSS ¹³C NMR spectra are given.
