The material described by MgMg5SbC crystallizes in the orthorhombic Amm2 space group. The structure consists of two 02329_fluka atoms and two 7439-95-4 atoms inside a Mg5Sb framework. In the Mg5Sb framework, there are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted linear geometry to two equivalent Sb(1) atoms. In the second Mg site, Mg(2) is bonded in a distorted water-like geometry to two equivalent Sb(1) atoms. In the third Mg site, Mg(4) is bonded in a distorted water-like geometry to two equivalent Sb(1) atoms. Sb(1) is bonded in a distorted q6 geometry to two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(2) atoms. is represented by the CIF file [CIF]
