α-氨基酸在人体有极为重要的生理作用,近年来人们对其稀土配合物进行了广泛的研究。进一步研究稀土氨基酸配合物的单晶结构对于探讨稀土离子与生物体的作用是很有意义的。将高氯酸钐溶液与生化试剂DL-a-缬氨酸以1:1摩尔比混合,在75℃水浴中反应6小时,加热浓缩后,室温下缓慢挥发,即得到浅黄色透明棱状晶体。 结果与讨论
α-amino acids in the human body has a very important physiological role in recent years, people have conducted extensive research on its rare earth complexes. Further study of the single crystal structure of rare earth amino acid complexes is very meaningful for exploring the role of rare earth ions and organisms. The samarium perchlorate solution and the biochemical reagent DL-a-valine were mixed in a molar ratio of 1: 1, reacted in a water bath at 75 ° C. for 6 hours, concentrated by heating, and slowly evaporated at room temperature to obtain a light yellow transparent prismatic crystal .
