title: Hafnium germanium telluride.
abstract: The title hafnium germanium telluride, HfGeTe(4), has been synthesized by the use of a halide flux and structurally characterized by X-ray diffraction. HfGeTe(4) is isostructural with stoichiometric ZrGeTe(4) and the Hf site in this compound is also fully occupied. The crystal structure of HfGeTe(4) adopts a two-dimensional layered structure, each layer being composed of two unique one-dimensional chains of face-sharing Hf-centered bicapped trigonal prisms and corner-sharing Ge-centered tetra-hedra. These layers stack on top of each other to complete the three-dimensional structure with undulating van der Waals gaps.
