Germanium dibromide is a bromide of germanium with the chemical formula GeBr2.

Preparation

Germanium dibromide can be obtained by reducing germanium tetrabromide with germanium or zinc.[4][1]

Properties

Germanium dibromide is a yellow-white solid that is soluble in

cyclopentadienylsodium or cyclopentadienylthallium in ether solvent to form germanocene.[7]
