SrLa2O4 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent La sites. In the first La site, La(1) is bonded to one O(1), two equivalent O(4), and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing LaO6 octahedra. The corner-sharing octahedral tilt angles range from 52-69°. In the second La site, La(2) is bonded to one O(4), two equivalent O(1), and three equivalent O(3) atoms to form a mixture of corner and edge-sharing LaO6 octahedra. The corner-sharing octahedral tilt angles range from 52-69°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Sr(1), one La(1), and two equivalent La(2) atoms. In the second O site, O(2) is bonded to two equivalent Sr(1) and three equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing OSr2La3 trigonal bipyramids. In the third O site, O(3) is bonded to two equivalent Sr(1) and three equivalent La(2) atoms to form a mixture of corner and edge-sharing OSr2La3 square pyramids. In the fourth O site, O(4) is bonded to two equivalent Sr(1), one La(2), and two equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing OSr2La3 trigonal bipyramids.
