Abstract New rare earth coordination compounds of salicylaldehyde Schiff base with β-alanine were synthesized and characterized by using elemental analysis and thermogravimetry, and their compositions have the formula, LnL 3 ·xH 2 O, where x = 3, Ln = La, Sm; x = 2.5, Ln = Gd; x = 2. Ln = Nd; x = 1.5, Ln = Ce, Pr, Eu; L = OH-C 6 H 4 -CHN-CH 2 -CHz-COO − . IR spectra, molar conductance and solubility
摘要 合成了水杨醛席夫碱与β-丙氨酸的新型稀土配位化合物,采用元素分析和热重法表征,其组成为LnL 3 ·xH 2 O,其中x=3,Ln=La,Sm;x = 2.5,Ln = Gd;x = 2。Ln = Nd;x = 1.5,Ln = Ce,Pr,Eu;L = OH-C 6 H 4 -CHN-CH 2 -CHZ-COO - 。利用DTA-TG-DTG和IR技术研究了配位化合物的红外光谱、摩尔电导和溶解度,并研究了它们的脱水和分解行为。
