The material described by Na2MgSn crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded in a 11-coordinate geometry to four equivalent Na(1), three equivalent Mg(1), and four equivalent Sn(1) atoms. Mg(1) is bonded in a distorted trigonal planar geometry to six equivalent Na(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a 11-coordinate geometry to eight equivalent Na(1) and three equivalent Mg(1) atoms. is represented by the CIF card [CIF]
