Highly stable chiral cadmium 1,2,4-benzenetricarboxylate: Synthesis, structure, and NLO and fluorescence properties

A 3-D chiral cadmium coordination polymer [Cd2(OH)(1,2,4-BTC)] is prepared under hydrothermal conditions using an unsymmetrical 1,2,4-benzenetricarboxylate (1,2,4-BTC) and characterized by single crystal X-ray diffraction and the 1,2,4-BTC ligand is found to show an unprecedented coordination mode. The compound exhibits intense photoluminescence at room temperature and shows distinct NLO properties.
