The material structure described by Lu2Cu2O5 is Spinel-like structured and crystallizes in the orthorhombic Pna2_1 space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(5) atoms to form a mixture of corner and edge-sharing LuO6 octahedra. The corner-sharing octahedral tilt angles range from 18-63°. In the second Lu site, Lu(2) is bonded to one O(3), one O(5), two equivalent O(1), and two equivalent O(4) atoms to form a mixture of corner and edge-sharing LuO6 octahedra. The corner-sharing octahedral tilt angles range from 18-63°. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), one O(4), and one O(5) atom. In the second Cu site, Cu(2) is bonded in a rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(5) is bonded to one Lu(2), two equivalent Lu(1), and one Cu(1) atom to form OLu3Cu tetrahedra that share corners with two equivalent O(5)Lu3Cu tetrahedra, corners with four equivalent O(1)Lu3Cu tetrahedra, corners with three equivalent O(2)Lu2Cu2 trigonal pyramids, corners with three equivalent O(4)Lu2Cu2 trigonal pyramids, and  an edgeedge with one O(2)Lu2Cu2 trigonal pyramid. In the second O site, O(1) is bonded to one Lu(1), two equivalent Lu(2), and one Cu(2) atom to form OLu3Cu tetrahedra that share corners with two equivalent O(1)Lu3Cu tetrahedra, corners with four equivalent O(5)Lu3Cu tetrahedra, corners with three equivalent O(2)Lu2Cu2 trigonal pyramids, corners with three equivalent O(4)Lu2Cu2 trigonal pyramids, and  an edgeedge with one O(4)Lu2Cu2 trigonal pyramid. In the third O site, O(2) is bonded to two equivalent Lu(1), one Cu(1), and one Cu(2) atom to form OLu2Cu2 trigonal pyramids that share corners with three equivalent O(1)Lu3Cu tetrahedra, corners with three equivalent O(5)Lu3Cu tetrahedra, corners with two equivalent O(2)Lu2Cu2 trigonal pyramids,  an edgeedge with one O(5)Lu3Cu tetrahedra, and  an edgeedge with one O(4)Lu2Cu2 trigonal pyramid. In the fourth O site, O(3) is bonded in a distorted see-saw-like geometry to one Lu(1), one Lu(2), one Cu(1), and one Cu(2) atom. In the fifth O site, O(4) is bonded to two equivalent Lu(2), one Cu(1), and one Cu(2) atom to form OLu2Cu2 trigonal pyramids that share corners with three equivalent O(1)Lu3Cu tetrahedra, corners with three equivalent O(5)Lu3Cu tetrahedra, corners with two equivalent O(4)Lu2Cu2 trigonal pyramids,  an edgeedge with one O(1)Lu3Cu tetrahedra, and  an edgeedge with one O(2)Lu2Cu2 trigonal pyramid. is represented by the CIF card [CIF]
