Two novel luminescent Cd(II)/Zn(II) coordination polymers based on 4,4′-(1H-1,2,4-triazol-1-yl)methylene-bis(benzonic acid) for sensing organic molecules and Fe3+ ion

Abstract

Two novel coordination polymers, {[Cd(TZMB)(1,4-bib)0.5]·(H2O)1.5} (1) and {[Zn(TZMB)(1,4-bib)0.5]}n (2), have been synthesized under solvothermal conditions. Complex 1 displays a 3D structure with the (47.84)(4.72.83) topology and Complex 2 is a 3D structure with the point symbol of {4.82}{4.85}. And complex 1 shows good luminescent quenching effect for organic solvent molecules (actone and p-nitrophenol) and Fe3+.
