A binuclear samarium(III) complex with benzoic acid and 1,10‐phenanthroline, [Sm(BA) 3 phen] 2 was synthesized and characterized by elemental analysis, UV, IR and TG‐DTG techniques. The structure of the title complex was established by single crystal X‐ray diffraction. The crystal is triclinic, space group P1 with a = 10.8216(11) Å, b = 11.9129(13) Å, c = 12.425(2) Å, α = 105.007(2)°, β = 93.652(2)°, γ = 113.2630(10)°, Z = 1, D c = 1.650 mg·m −3 , F (000) = 690. The carboxylate groups are bonded to the samarium ion in three modes: bidentate chelating, bidentate bridging, and tridentate chelating‐bridging. Each Sm 3+ ion is coordinated to one bidentate chelating carboxylate group, two bidentate bridging and two tridentate chelating‐bridging carboxylate groups, as well as one 1,10‐phenanthroline molecule, forming a nine‐coordinate metal ion. Based on thermal analysis, the thermal decomposition process of [Sm(BA) 3 phen] 2 has been derived.
