Two novel lead-carboxylate complexes based on nicotinic acid N-oxide: Synthesis, crystal structures and luminescent properties

Two new lead-carboxylate complexes based on nicotinic acid N-oxide ligand, [Pb(NNO)(FA)0.5] (1) (HNNO = nicotinic acid N-oxide, FA = fumaric acid) and [Pb2(NNO)(BTC)] (2) (H3BTC = 1,3,5-benzenetricarboxylic acid) were hydrothermally synthesized and characterized by the elemental analyses, IR spectra and single crystal X-ray diffraction. Significant phosphorescent properties of two compounds were observed at room temperature.

Graphical abstractReaction of lead(II), nicotinic acid N-oxide (NNO) and different carboxylate acid (fumaric acid or 1,3,5-benzenetricarboxylic acid) gives a 1D zig-zag chain and a 3D network structure. Moreover, two compounds both exhibit good room-temperature phosphorescence emissions.Figure optionsDownload full-size imageDownload as PowerPoint slide
