摘要
A new coordination polymer [Zn3(bpda)3(bpy)] 1 (H2bpda = 2,2'-biphenyldicar- boxylic acid, bpy = 4,4'-bipyridien) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction analysis, elemental analysis, TG analysis and IR spectrum. 1 Crystallizes in cubic crystal system, space group Ia 3, with a = 20.9687(9) A, V = 9219.7(3) A^3, Z = 8, and R(I 〉 2σ(I)) = 0.0431. Complex 1 is a three-dimensional framework involving a new building block, linear trinuclear {Zn3(CO2)6N2} cluster. In the structure, each bpda coordinates to four zinc atoms via its two bridging bidentate carboxylate groups. To the best of our knowledge, 1 implies a new coordination mode of 2,2'-biphenyldicarboxylic acid. The solid state fluorescent spectra show a strong emission peak at 451 nm (λex= 341 nm).
