The structure described by In2Cu2O5 is Spinel-like structured and crystallizes in the orthorhombic Pna2_1 space group. 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 distorted rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are two inequivalent In sites. In the first In site, In(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 edge and corner-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 18-63°. In the second In site, In(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 edge and corner-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 18-63°. There are five inequivalent O sites. In the first O site, O(5) is bonded to one Cu(1), one In(2), and two equivalent In(1) atoms to form distorted OIn3Cu tetrahedra that share corners with two equivalent O(5)In3Cu tetrahedra, corners with four equivalent O(1)In3Cu tetrahedra, corners with three equivalent O(2)In2Cu2 trigonal pyramids, corners with three equivalent O(4)In2Cu2 trigonal pyramids, and  an edgeedge with one O(2)In2Cu2 trigonal pyramid. In the second O site, O(1) is bonded to one Cu(2), one In(1), and two equivalent In(2) atoms to form distorted OIn3Cu tetrahedra that share corners with two equivalent O(1)In3Cu tetrahedra, corners with four equivalent O(5)In3Cu tetrahedra, corners with three equivalent O(2)In2Cu2 trigonal pyramids, corners with three equivalent O(4)In2Cu2 trigonal pyramids, and  an edgeedge with one O(4)In2Cu2 trigonal pyramid. In the third O site, O(2) is bonded to one Cu(1), one Cu(2), and two equivalent In(1) atoms to form OIn2Cu2 trigonal pyramids that share corners with three equivalent O(1)In3Cu tetrahedra, corners with three equivalent O(5)In3Cu tetrahedra, corners with two equivalent O(2)In2Cu2 trigonal pyramids,  an edgeedge with one O(5)In3Cu tetrahedra, and  an edgeedge with one O(4)In2Cu2 trigonal pyramid. In the fourth O site, O(3) is bonded in a 4-coordinate geometry to one Cu(1), one Cu(2), one In(1), and one In(2) atom. In the fifth O site, O(4) is bonded to one Cu(1), one Cu(2), and two equivalent In(2) atoms to form OIn2Cu2 trigonal pyramids that share corners with three equivalent O(1)In3Cu tetrahedra, corners with three equivalent O(5)In3Cu tetrahedra, corners with two equivalent O(4)In2Cu2 trigonal pyramids,  an edgeedge with one O(1)In3Cu tetrahedra, and  an edgeedge with one O(2)In2Cu2 trigonal pyramid. is represented by the CIF file [CIF]
