Description
Dimagnesium copper, Mg2Cu, Mr=112.170, orthorhombic, Fddd (70), a=5.275(1), b=9.044(1), c=18.328(2) A, V=874.3(2) A3, Z=16, Dx=3.41 g cm-3, Mo Kα (λ=0.71073 A), μ=101.145 cm-1, F(000)=848, T=293 K, R=0.034 (wR=0.031) for 17 refined parameters and 310 observed X-ray single-crystal reflections [F0>3σ(F0)]. The refined parameters are consistent with the nonrefined parameters reported by Schubert and Anderko. The Mg2Cu structure type can be derived by a stacking of slabs that build up the Al2Cu and Mg2Ni structure types. (orig.)
