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 CaGe 2 films at –30 °C. Polygermyne is found to exhibit strong near‐infrared photoluminescence with an intensity comparable to that of siloxene, its silicon homologue.
