Synthesis and Luminescence of Optical Memory Active Tetramethylammonium Cyanocuprate(I) 3D Networks.

The structures of three tetramethylammonium cyanocuprate(I) 3D networks [NMe][Cu(CN)]•0.25HO (), [NMe][Cu(CN)] (), and [NMe][Cu(CN)] (), (MeN = tetramethylammonium), and the photophysics of and are reported. These complexes are prepared by combining aqueous solutions of the simple salts tetramethylammonium chloride and potassium dicyanocuprate.
