The title compound, NH4ScF4, is an addition to the AMF(4) family of layered perovskite-like structures. The structure consists of a two-dimensional array of corner-sharing ScF6 octahedra, which produces anionic sheets of stoichiometry [ScF4]. stacked along the c axis. The layers are separated by charge-balancing ammonium cations, which hydrogen bond to the apical F atoms of adjacent layers. This structure may be viewed as a 'single-layer' fluoride analogue of the Dion-Jacobson family of oxides.
