【Abstract】 A complex [ZnL2( CH3CN)2Cl2]( L = 2,3-bis( 1,2,4-triazole) quinoxaline) was synthesized in 50% methyl cyanide / ethanol solution at room temperature and the structure was confirmed by elemental analysis,IR and single crystal X-ray diffraction analysis. The complex belongs to monoclinic system,space group C2 / c,a = 17. 665(3) ,b =23. 661(5) ,c = 7. 473 7(15) ,β = 96. 62( 3) °,V =3 103. 0(10) 3,Z =4,D c= 1. 599 g / cm3,μ = 1. 02 mm- 1,F( 000) = 1 520,the final R = 0. 0523,wR = 0. 135 9. The structure of polymer showes an unique three-dimensional supramolecular structure distorted with large channels by bridge linked of the ligand and π- π stacking. Moreover,the photoluminescence property of sample was investigated.更多还原
