title: Preparation, structure and near-infrared luminescent property of Yb(III) complex with 2,4,6-pyridinetricarboxylic acid.
abstract: A rare earth ytterbium complex with 2,4,6-pyridinetricarboxylic acid (H(3)pta) has been synthesized by hydrothermal method, the formula is {[Yb(2)(pta)(2)(H(2)O)(3)]·H(2)O}(n). The complex crystallized in monoclinic system, P2(1)/c space group with lattice parameters a = 11.6556(19)Å, b = 7.8364(12), c = 22.020(4), α = γ = 90º, β = 92.120(3), Z = 4, GOF = 1.026, R1 = 0.0334, wR2 = 0.0660. The pta anions connect four rare earth Yb(III) ions with two different coordination modes. The complex exhibit intense characteristic near-infrared luminescence of Yb(III) ions at 990 nm with excitation of UV-rays.
