硝酸钇与L-α-氨基酸固体配合物的合成与表征

Synthesis and characterization of solid coordination compounds of yttrium nitrate with L-α-amino acids

报道了4种在水溶液中合成的硝酸钇与L-α-色氨酸、L-α-缬氨酸固体配合物,经化学分析、元素分析以及热重分析,确定了其组成分别为Y(Val)2(NO3)3·2H2O、Y(Val)(NO3)·4H2O、Y(Try)2(NO3)3·4H2O和Y(Try)(NO3)3·2H2O,并测定了配合物的红外光谱,对配位情况进行了推测。

Four coordination compounds of yttrium nitrate with L-α-Valine and L-α-Tryptophan prepared from water were synthesized. Compositions and structures of the compounds were determined by chemical analysis,element analysis and thermogravimetrics analysis. The general formula of these complexes are Y(Val)_2(NO_3)_3·2H_2O,Y(Val)(NO_3)_3·4H_2O,(Y(Try)_2)(NO_3)·4H_2O,Y(Try)(NO_3)_3·2H_2O.IR spectra of the solid complexes were described. The coordination behavior of yttrium nitrate with L-α-amino acids was studied.
