A new europium(Ⅲ) complex Eu(C₂₀H₁₄O₃N)₃(2,2΄-bipy)(H₂O)·H₂O has been synthesized with 2-diphenylanine carbonyl benzoic acid and 2,2΄-bipyridine as ligands. Crystal data for the complex are as follows: triclinic, space group P, a = 11.3334(5), b = 16.0883(7), c = 17.0116(8) Å, α = 70.411(4)º, β = 82.435(4)º, γ = 85.095(4)º, V = 2894.0(2) ų, D_c = 1.484 g/cm³, Z = 2, μ = 1.15 mm^-1, F(000) = 1320 and the final R = 0.0447 and wR = 0.0578. The Eu(Ⅲ) ion is coordinated by nine atoms to give a monocapped square antiprism coordination geometry. The complex shows two intense fluorescence emission bands arising from the transitions of Eu³⁺: ⁵D₀ → ⁷F₁ (592 nm) and ⁵D₀ → ⁷F₂ (616 nm), respectively. Also reported is the magnetic property of the complex. The complex exhibits antiferromagnetism in the temperature range of 300～2 K.
