Abstract:

Two mixed-metal coordination polymers, [In(OH)Cu(TBA)2(C2H6OH)]·NMF(1) and [In0.5Cd0.5(TBA)(CH3OH)][NO3]0.5·2NMF(2)[H2TBA=4-(1H-tetrazol-5-yl)-benzoic acid, NMF=N-methylformamide], were synthesized under solvothermal conditions and characterized by elemental analysis, powder X-ray diffraction(PXRD), thermogravimetric analysis(TGA) and single crystal X-ray diffraction. Complex 1 has a neutral 3D framework formed from the infinite chains and four-coordinated mononuclear Cu by TBA ligands. Compared to complex 1, In and Cd centers in complex 2 have the same infinite chains, which are bridged by TBA ligands to produce a cationic 3D structure. Complex 1 possesses a (4,4,8)-connected new topology while complex 2 belongs to (4,8)-connected topology. Notably, complex 2 can be used to detect Li+ and Fe3+ through either fluorescence enhancement or quenching effect, respectively. Thus complex 2 may be considered as a potential luminescent probe for the detection of Li+ and Fe3+.
