One new Zn(Ⅱ) complex [Zn_2(cptpy)_2(tzba)(H_2O)]·H_2O(1, Hcptpy = 4-(4-carboxyphenyl)-2,2?:4?,4??-terpyridine(Hcptpy), H_2tzba = 4-(tetrazol-5-yl)benzenecarboxylic acid) has been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction techniques. It is formulated as C52H36O8N10Zn2, crystallizes in monoclinic system, space group P21/c with α = 15.1599(13), b = 28.083(2), c = 10.9039(9) ?, b = 97.517(8)o. V = 4602.3(6) ?3, Z = 4, Mr = 1059.68, Dc = 1.529 g/cm~3, F(000) = 2168 and μ = 1.112 mm-1. The final R = 0.0831 and w R = 0.2143 for 8458 observed reflections with I > 2s(I). The assembly of polyfunctional organic ligands Hcptpy and H_2tzba with Zn(II) atoms resulting in a rare example of double-edge ladders, which is further extended into a 3D supramolecular network via O–H···O/N hydrogen bonds. In addition, thermal gravimetric analysis(TGA) and PXRD patterns for 1 were studied. Photo luminescent property of 1 was also investigated.
