Tetrakis(tert-butyl isocyanide)copper(I) chloride monohydrate

W. Imhof, K. Halbauer and H. Görls

Abstract: The title compound, [Cu(C₅H₉N)₄]Cl·H₂O, was obtained from the reaction of copper(II) chloride hydrate with KCN in the presence of two equivalents of tert-butylisocyanide. The reaction proceeds via the reduction of copper and the formation of (CN)₂. The compound shows a tetrahedrally surrounded Cu^I centre, with the Cu^I ion and the water O atom being situated on crystallographic twofold axes. The crystal structure contains infinite chains of alternating solvent molecules and Cl^- anions, with additional weak C-HCl or C-HO interactions with the [Cu(CN^tBu)₄] cations.
