Poly[di­ethyl­ammonium [tetra-μ2-cyanido-κ8C:N-tricuprate(I)]], a two-dimensional network solid

ABSTRACT: The title compound crystallizes as a CuCN network solid, with di­ethyl­ammonium cations sandwiched between two-dimensional, planar CuCN sheets comprised of trigonally and digonally coordinated Cu atoms in 24-membered rings. The title compound, (C4H12N)[Cu3(CN)4]n, crystallizes as a CuCN network solid, with di­ethyl­ammonium cations sandwiched between planar CuCN sheets comprised of trigonal planar and digonally coordinated CuI atoms bridged by linear CN groups to form 24-membered rings. The digonally coordinated CuI atoms and the di­ethyl­ammonium cations lie on separate crystallographic twofold rotation axes. One of the two independent CN groups has a 50:50 disordered orientation, while the other has one orientation favored due to a N—H⋯NC hydrogen bond between the di­ethyl­ammonium cation and the anionic CuCN framework. These hydrogen bonds link the sheets together into a three-dimensional network.
