The complex [Dy(BAA)2(phen)NO3]2 (HBAA = phenylacetic acid, phen = 1,10-phenanthroline) was synthesized under hydrothermal conditions and characterized as by elemental analyses, IR, UV, fluorescence excitation and emission spectroscopy. A single-crystal X-rays structure determination diffraction indicates that the complex is dimeric and Dy has a coordination number of nine. The coordination polyhedron can be described as a distorted, monocapped, square antiprism. Pairs of adjacent metal atoms are bridged by four BAA groups in two coordination modes. The complex is triclinic system, space group P [image omitted], with a = 8.953(6), b = 13.312(9), c = 13.408(9) Å, α = 60.608(7), β = 89.674(9), γ = 72.165(9)°, V = 1305.0(15) Å3, Dc = 1.718 mg m-3, Z = 1, F(000) = 666, R1 = 0.0424.
