The compound described by EuLu2O4 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to one O(4), two equivalent O(2), 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 50-62°. In the second Lu site, Lu(2) is bonded to one O(2), two equivalent O(4), and three equivalent O(1) atoms to form a mixture of corner and edge-sharing LuO6 octahedra. The corner-sharing octahedral tilt angles range from 50-62°. Eu(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 four inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Lu(2) and two equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing OEu2Lu3 trigonal bipyramids. In the second O site, O(2) is bonded to one Lu(2), two equivalent Lu(1), and two equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing OEu2Lu3 trigonal bipyramids. In the third O site, O(3) is bonded to three equivalent Lu(1) and two equivalent Eu(1) atoms to form a mixture of corner and edge-sharing OEu2Lu3 square pyramids. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to one Lu(1), two equivalent Lu(2), and two equivalent Eu(1) atoms. is represented by the CIF file [CIF]
