Germanium monoxide, GeO, is a chemical compound of germanium and oxygen. It can be prepared as a yellow sublimate at 1000°C by reacting GeO2 with Ge metal. The yellow sublimate turns brown on heating at 650°C.[1]. GeO is not well characterised.[1] It is amphoteric dissolving in acids to form germanium(II) salts and in alkali to form "trihydroxogermanates" or "germanites" containing the Ge(OH)3− ion.[2]
