MgCu2 is a binary intermetallic compound of magnesium (Mg) and copper (Cu) adopting cubic crystal structure, more specifically the C15 Laves phase. The space group of MgCu2 is Fd3m with lattice parameter a = 7.04 Å. [2]
MgCu2 can be prepared by hydrogenation of Mg2Cu or the reaction of magnesium hydride and metallic copper at elevated temperature and pressure: [3]
MgCu2 can also be prepared by reacting of stoichiometric amounts of metals at about 380 °C in the presence of excess copper. [4]
MgCu2 can react with boron or its oxide to form magnesium borides. [5] It can also react with magnesium hydride to produce orthorhombic Mg2Cu, liberating hydrogen. [6]
