Abstract:

One mixedligand complex of [Zn(tpa)(tripy)]_n·_nH_2O( tpa=terephthalate, tripy=4′-(4-methyoxyphenyl)-2,2′∶6′,2″-terpyridine)\] was synthesized and characterized by IR, elemental analysis and thermo gravimetric analysis. The crystal structure of the product was established by single crystal X-ray diffraction. It is a onoclinic crystal with space group P21/c. a＝0.855 0(2) nm,b＝2.825 0(6) nm,c＝1.096 0(2) nm,β＝107.14(3)°,V＝2.529 7(9) nm³,Z＝4,D_c＝1.541 g/cm³,M_r＝586.88,F(000)＝1 208. The complex consists of onedimensional Zigzag chain. Compared with the ligand, the complex exhibits intense photoluminescence.
