The structure described by SrCu2Sb2 crystallizes in the tetragonal P4/nmm space group. Sr(1) is bonded in a 16-coordinate geometry to four equivalent Cu(1), four equivalent Cu(2), four equivalent Sb(1), and four equivalent Sb(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Sb(1), and four equivalent Sb(2) atoms. In the second Cu site, Cu(2) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Cu(1), and four equivalent Cu(2) atoms. In the second Sb site, Sb(2) is bonded in a 4-coordinate geometry to four equivalent Sr(1) and four equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
