The structure described by Mn3Sn2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 11-coordinate geometry to two equivalent Mn(1), three equivalent Mn(2), three equivalent Sn(1), and three equivalent Sn(2) atoms. In the second Mn site, Mn(2) is bonded to six equivalent Mn(1), two equivalent Sn(2), and three equivalent Sn(1) atoms to form a mixture of distorted corner and face-sharing MnMn6Sn5 trigonal bipyramids. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to three equivalent Mn(2) and six equivalent Mn(1) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to two equivalent Mn(2) and six equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
