Polymeric Networks of Silver(I) and Copper(I) Ions Linked by an Anionic Acetonyl Derivative of Tetracyanoethylene

Unexpectedly, the reaction of tetracyanoethylene (TCNE) with acetone yields a tetracyanopentanonide that forms interesting coordination polymers with AgI and CuI ions. [Ag(AcTCNE)] is a layer structure consisting of twofold interpenetrated 2D nets of hexagonal meshes, while [Cu(AcTCNE)]·Me2CO consists of a zeolite-like 3D network, whose large channels contain guest acetone molecules (shown on the right).
