SrCaSi crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. Ca(1) is bonded to four equivalent Si(1) atoms to form a mixture of distorted corner and edge-sharing CaSi4 tetrahedra. Si(1) is bonded in a 9-coordinate geometry to five equivalent Sr(1) and four equivalent Ca(1) atoms.
