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

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 atom...

Description
Summary: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.
