钐β-丙氨酸配合物单晶的制备及表征

Synthesis and Characterization of Samarium Complex with β-Alanine

报道了钐β-丙氨酸配合物单晶的制备,并用元素分析、热分析、红外光谱和量子化学计算方法研究了该配合物的组成、性质、化学键特点及其电子结构.

The single crystal of a samarium complex of β-alanine has been synthesized, and its composition, properties, characters of chemical bond as well as electronic structure have been investigated by elemental analysis, TG-DTA, IR spectrum and quantum chemical calculation. The ligand is coordinated to the samarium ion only via its carboxyl group. The coordination bonds between the ligand and samarium ion are poredominantly ionic, but have certain covalency. The contribution to covalent bonding is mainly due to the 5d orbitals os the samarium ion, while the 4f orbitals are strongly localized.
