2‑Acyl-1,1,3,3-tetracyanopropenides (ATCN): structure characterization and luminescent properties of ammonia and alkali metal ATCN salts

Abstract

The syntheses and crystal structures and photoluminescence properties of 24 new ammonia and alkali metals ATCN salts characterized via single-crystal X-ray diffraction are reported. Ten structure types of these salts are described, three of which are predominant. Some ATCN were obtained as two crystalline polymorphs. It was estimated, that most ATCN powders exhibit yellow-green fluorescence (at 450 – 600 nm). For samples, which possess fluorescence of a low intensity in the solid state, several optical centers of emission exist. It was assumed, that obtained spectral features are due to anion-anion intermolecular interactions. ATCN are new representatives of stable tetracyanoallyl salts that make it a promising candidate for creation of various 1D, 2D, and 3D supramolecular structures and potential functional materials
