The structure described by Na2CdSn crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded in a 7-coordinate geometry to three equivalent Cd(1) and four equivalent Sn(1) atoms. Cd(1) is bonded in a 9-coordinate 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 Cd(1) atoms. is represented by the CIF file [CIF]
