. 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.
GeO is not well characterised.
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.
