One new Zn(II) complex [Zn2(cptpy)2(tzba)(H2O)]•H2O (1, Hcptpy = 4-(4-car- boxyphenyl)-2,2΄:4΄,4΄΄-terpyridine (Hcptpy), H2tzba = 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) Å, = 97.517(8)º. V = 4602.3(6) Å3, Z = 4, Mr = 1059.68, Dc = 1.529 g/cm3, F(000) = 2168 and µ = 1.112 mm-1. The final R = 0.0831 and wR = 0.2143 for 8458 observed reflections with I > 2(I). The assembly of polyfunctional organic ligands Hcptpy and H2tzba 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.
