Germanium dibromide is a bromide of germanium with the chemical formula GeBr2.
Germanium dibromide can be obtained by reducing germanium tetrabromide with germanium or zinc. [4] [1]
Germanium dibromide is a yellow-white solid that is soluble in ethanol and acetone. It disproportionates into germanium tetrabromide and germanium. [1] [5] It hydrolyzes to germanium dihydroxide. [4] Germanium dibromide is monoclinic, space group P21/c (No. 14), lattice parameters a = 11.68 Å, b = 9.12 Å, c = 7.02 Å, and β = 101.9°. [6] It can react with cyclopentadienylsodium or cyclopentadienylthallium in ether solvent to form germanocene. [7]
