The material described by Pr2Sb crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 4-coordinate geometry to four equivalent Sb(1) atoms. In the second Pr site, Pr(2) is bonded to five equivalent Sb(1) atoms to form a mixture of distorted edge and corner-sharing PrSb5 square pyramids. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1) and five equivalent Pr(2) atoms. is represented by the CIF card [CIF]
