The structure described by Sr5Sn3 crystallizes in the monoclinic C2/c space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to two equivalent Sn(2) and three equivalent Sn(1) atoms to form a mixture of distorted face, corner, and edge-sharing SrSn5 trigonal bipyramids. In the second Sr site, Sr(1) is bonded to two equivalent Sn(2) and three equivalent Sn(1) atoms to form a mixture of distorted face, corner, and edge-sharing SrSn5 trigonal bipyramids. In the third Sr site, Sr(2) is bonded in a square co-planar geometry to four equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to two equivalent Sr(2); six Sr(1,1); and one Sn(1) atom. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to eight Sr(1,1) atoms. is represented by the CIF card [CIF]
