The material described by Sr2Sb crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted square co-planar geometry to four equivalent Sb(1) atoms. In the second Sr site, Sr(2) is bonded to five equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing SrSb5 square pyramids. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1) and five equivalent Sr(2) atoms. is represented by the CIF card [CIF]
