Description
Summary:Peculiar coordination compound Cu(Hbpt)(CH 3 CN) 2 PF 6 ( 1 ) derived from 3,5-bis(4-pyridyl)-1 H -1,2,4-triazole (Hbpt) is synthesized by the layer diffusion method and structurally characterized by single crystal and powder X-ray diffraction, elemental analysis, and infrared spectroscopy. Compound 1 exhibits a structure formed by cationic chains and anions with abundant supramolecular interactions. Solid-state photoluminescence experiments show that compound 1 exhibits relatively strong red emission with a peak around 656 nm, and the origin of the emission band may be ascribed to the metal-to-ligand charge transfer according to the calculation of the density of states.
