Negative area compressibility in silver(I) tricyanomethanide

Abstract

The molecular framework Ag(tcm) (tcm${}^{-}$ = tricyanomethanide) expands continuously in two orthogonal directions under hydrostatic compression. The first of its kind, this negative area compressibility behaviour arises from the flattening of honeycomb-like layers during rapid pressure-driven collapse of the interlayer separation.
