Multistep Reversible Redox Systems, LI. - A Facile Method for the Preparation of Large Single Crystals of Highly Conductive Copper Salts of N,N′-Dicyanoquinone DiiminesOn reaction of acetonitrile solutions of substituted N,N′-dicyanoquinone diimines (R1-4-DCNQIs) with bright copper wires, the sparingly soluble copper salts (R1-4-DCNQI)nCu are formed. They deposit in most cases as crystals of 3-30 mm in length of equal quality to those produced by electro crystallisation. This more elaborate method can therefore be abandoned.
Notes:
Durch Eintauchen eines blanken Kupferdrahtes in Acetonitrillösungen substituierter N,N′-Dicyanchinondiimine (R1-4-DCNQIs) entstehen die schwer löslichen Kupfersalze (R1-4-DCNQI)nCu meist als Einkristalle von 3-30 mm Länge. Ihre Qualität entspricht der durch Elektrokristallisation erhaltenen, so daß diese wesentlich aufwendigere Methode entbehrt werden kann.
