文摘
The self-assembly of a prominent mixed-donor ligand, 5-[4-(1H-tetrazolyl)phen]isophthalic acid(H3TZPI), with a Cd2+ center generates two new metal-organic frameworks: [Cd(H2TZPI)2(H2O)2]n(JUC-163) and [Cd2(TZPI)(μ3-OH)(H2O)2]·H2O·DMF(JUC-164). The two complexes demonstrate different structures for the ligand’s different coordination modes and configurations. JUC-163 shows a 2D layer structure and further forms into a 3D supramolecular framework by noncovalent interactions(C―H···O, O―H···N and π···π interactions), whereas JUC-164 exhibits a fascinating 3D framework for the outstanding coordination modes and configurations of the ligand, which are fit for the complex structure. And also, the factor of different cadmium salts(chloride and nitrate) which are used in synthesis progress is worth to notice for the construction of the two distinct structures. The luminescent properties of these metal-organic frameworks are also investigated.KeywordsCadmiumMixed-donor ligandMetal-organic frameworkLuminescence
