Abstract: 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, IRspectrum 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.

Key words: Samarium, β-Alanine, Complex
