Crystalline polygermyne—a new compound consisting of H-terminated germanium double layers (see Figure) stacked to form a three-dimensional crystal—is reported to have been produced by the topochemical transformation of epitaxial thin CaGe2 films at –30 °C. Polygermyne is found to exhibit strong near-infrared photoluminescence with an intensity comparable to that of siloxene, its silicon homologue.
