A dinuclear dysprosium(Ⅲ) complex with benzoic acid and 1,10-phenanthroline, [Dy(BA)3phen]2 (BA = benzoate, PHEN = 1,10-phenanthroline) (C66H46Dy2N4O12, Mr = 1412.07) was synthesized and characterized by elemental analysis, UV, IR, X-ray diffraction, molar conductance and TG-DTG techniques. It crystallizes in triclinic, space group P1 with a = 10.773(2), b = 11.933(3), c = 12.417(5) , α = 105.226(3), β = 93.470(3), γ = 113.475(2)o, V = 1388.0(7), Z = 1, Dc = 1.689 g/cm3, μ(MoKa) = 2.742 mm-1 and F(000) = 698. R = 0.0210, wR = 0.0538. In the crystal, each Dy(III) ion is eight-coordinated by one bidentate chelating carboxylate group, four bidentate bridging carboxylate groups and one 1,10-phenanthroline molecule. The thermal decomposition process of [Dy(BA)3phen]2 has been determined by thermal analysis.
