- 中文摘要: A binuclear samarium(III) complex with benzoic acid and 1,10-phenanthroline, [Sm(BA)3phen]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) A, b = 11.9129(13) A, c = 12.425(2) A, a = 105.007(2)°, b = 93.652(2)°, g = 113.2630(10)°, Z = 1, Dc = 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 Sm3+ 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)3phen]2 has been derived.
