Abstract
A novel layered MOF, {[Pb2(H2Bic)(HBic)Cl3] · 2H2O} n (I), was hydrothermally obtained by the reaction of PbCl2 with 1-H-benzimidazole-5-carboxylic acid (H2Bic) and fully characterized by single-crystal X-ray diffraction, elemental analysis, FT-IR, TG-DTA, and luminescent spectra. Structural analysis suggests that complex I is a 2D layer assembled from helical Pb(II)-HBicchains and bridging chloride linkers, which is H-bonded together into a 3D supramolecular network. Additionally, I in the solid-state exhibits a favorable fluorescent emission at room temperature due to the intraligand charge transfer, suggesting its potential application as fluorescence materials.
