The material structure described by SrMnSb2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Sb(1) and four equivalent Sb(2) atoms. Mn(1) is bonded to four equivalent Sb(2) atoms to form a mixture of corner and edge-sharing MnSb4 tetrahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Sb(1) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Mn(1) atoms. is represented by the CIF card [CIF]
