The compound described by SrNiSn3 crystallizes in the tetragonal I4mm space group. Sr(1) is bonded in a 17-coordinate geometry to five equivalent Ni(1), four equivalent Sn(1), and eight equivalent Sn(2) atoms. Ni(1) is bonded in a 5-coordinate geometry to five equivalent Sr(1), one Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Ni(1), and four equivalent Sn(2) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Sr(1), two equivalent Ni(1), and two equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
