SrLu2O4 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 Lu sites. In the first Lu site, Lu(1) is bonded to one O(1), two equivalent O(4), and three equivalent O(2) atoms to form a mixture of corner and edge-sharing LuO6 octahedra. The corner-sharing octahedral tilt angles range from 50-61°. In the second Lu site, Lu(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 LuO6 octahedra. The corner-sharing octahedral tilt angles range from 50-61°. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), one Lu(1), and two equivalent Lu(2) atoms to form a mixture of distorted corner and edge-sharing OSr2Lu3 trigonal bipyramids. In the second O site, O(2) is bonded to two equivalent Sr(1) and three equivalent Lu(1) atoms to form a mixture of distorted corner and edge-sharing OSr2Lu3 trigonal bipyramids. In the third O site, O(3) is bonded to two equivalent Sr(1) and three equivalent Lu(2) atoms to form a mixture of corner and edge-sharing OSr2Lu3 square pyramids. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to two equivalent Sr(1), one Lu(2), and two equivalent Lu(1) atoms.
