Syntheses, structures and luminescence properties of three metal–organic frameworks based on 5-(4-(2H-tetrazol-5-yl)phenoxy)isophthalic acid

Abstract

Three metal–organic frameworks (MOFs), namely [Zn2(TPIA)(OH)(H2O)]·H2O (JUC-114), [Cd2(TPIA)(OH)(H2O)2]·H2O (JUC-115), and [Co2(TPIA)(OH)(H2O)2]·H2O (JUC-116) (JUC = Jilin University China), based on a new ligand, 5-(4-(2H-tetrazol-5-yl)phenoxy)isophthalic acid (H3TPIA), were synthesized under hydrothermal conditions and characterized by single crystal X-ray diffraction, elemental analysis, IR spectroscopy, TGA analysis and powder X-ray diffraction. JUC-114, JUC-115 and JUC-116 all possess 3D frameworks with (4,8)-connected fluorite (flu) topology based on similar tetranuclear metal centers as secondary building unit (SBU). Furthermore, the luminescence of the ligand H3TPIA and compounds was measured at room temperature.
