In the solid state it exists as a glass, with four-coordinate Be(2+) tetrahedral centres and two-coordinate fluoride centres. Reduction of BeF2 at 1300 °C with magnesium in a graphite crucible provides the most practical route to metallic beryllium: As a gas it adopts a linear triatomic structure and in the liquid state a fluctuating tetrahedral structure. : 232-118-5 Molecular formula: BeF2 Molecular weight: 47.009 Melting point: 545 ℃ Boiling point Other name: Beryllium difluoride CAS no. : 7787-49-7 EINECS no.
