The crystal structure described by SrMgPt crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 5-coordinate geometry to five equivalent Pt(1) atoms. Mg(1) is bonded to four equivalent Pt(1) atoms to form a mixture of distorted corner and edge-sharing MgPt4 tetrahedra. Pt(1) is bonded in a 9-coordinate geometry to five equivalent Sr(1) and four equivalent Mg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
