The crystal structure described by Mg4SnSi crystallizes in the cubic F-43m space group. The structure consists of four 7440-21-3 atoms inside a Mg4Sn framework. In the Mg4Sn framework, Mg(1) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a 12-coordinate geometry to twelve equivalent Mg(1) atoms. is represented by the CIF file [CIF]
