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. ; Comment: 3 pages, 2 figures, formatted for Chem Comm
