The material described by Fe3Sn2 crystallizes in the trigonal R-3m space group. Fe(1) is bonded in a 11-coordinate geometry to six equivalent Fe(1), two equivalent Sn(2), and three equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted q6 geometry to nine equivalent Fe(1) atoms. In the second Sn site, Sn(2) is bonded in a 6-coordinate geometry to six equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
