Crystal Structures of M(DCNQIs)2 (DCNQIs=N,N′-dicyanoquinonediimines; M=Li, Na, K, NH4, Cu, Ag)

Crystal structures of highly conducting title compounds were determined. The basic structure of all compounds consists of uniform face-to-face columns of acceptor molecules. These columns are connected to each other through N-coordinated cations. The geometry of coordination depends on the counter cation.
