Germanium monoxide

Germanium monoxide (chemical formula 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 to 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]
