Germanium dibromide is a bromide of germanium with the chemical formula GeBr<sub>2</sub>.
Germanium dibromide can be obtained by reducing germanium tetrabromide with germanium or zinc.
Germanium dibromide is a yellow-white solid that is soluble in ethanol and acetone. It disproportionates into germanium tetrabromide and germanium. It hydrolyzes to germanium dihydroxide. Germanium dibromide is monoclinic, space group P2<sub>1</sub>/c (No. 14), lattice parameters a = 11.68 à, b = 9.12 à, c = 7.02 à, and ò = 101.9ð. It can react with cyclopentadienylsodium or cyclopentadienylthallium in ether solvent to form germanocene.
