The material described by Pr2CdSe4 crystallizes in the tetragonal I-42d space group. Pr(1) is bonded in a 8-coordinate geometry to eight equivalent Se(1) atoms. Cd(1) is bonded in a distorted square co-planar geometry to four equivalent Se(1) atoms. Se(1) is bonded in a 5-coordinate geometry to four equivalent Pr(1) and one Cd(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
