The compound described by Sr2Pd is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to four equivalent Pd(1) atoms to form a mixture of corner and edge-sharing SrPd4 tetrahedra. In the second Sr site, Sr(2) is bonded in a 5-coordinate geometry to five equivalent Pd(1) atoms. Pd(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1) and five equivalent Sr(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
