Terbium perchlorate reacted with isonicotinic acid (Hpya) and biphenyl-2,2′-dicarboxylic acid (H_2dpa) under hydrothermal condition, a new ternary terbium complex [Tb(pya)(dpa)(H_2O)]_n (1) was synthesized. The structure of the ternary complex was determined by X-ray single crystal diffraction and characterized by elemental analysis, fluorescence measurement. The fluorescence spectrum shows the title complex emits strong green light. The crystal data for the complex: monoclinic, P2_1/n space group, a=0.8908(5) nm, b=1.0569(6) nm, c=2.0969(11) nm, β=98.446(8)°, V=1.9528(18) nm~3, Z=4, R=0.0241, wR_2=0.0534. The center Tb~ 3+ ion is eight coordinated. The coordination polyhedron around Tb~ 3+ ion can be described as a distorted square antiprism. The complex forms an infinite one-dimensional alternating chain polymer by bridging carboxyl groups of pya and dpa.
