Germanium dibromide explained

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.^[1]

Ge + GeBr4 -> 2GeBr2

Properties

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 P2₁/c (No. 14), lattice parameters a = 11.68 Å, b = 9.12 Å, c = 7.02 Å, and β = 101.9°. It can react with cyclopentadienylsodium or cyclopentadienylthallium in ether solvent to form germanocene.^[2]
