Eu(CuO2)2 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. Eu3+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. All Eu–O bond lengths are 2.49 Å. Cu+2.50+ is bonded in a square co-planar geometry to four equivalent O2- atoms. There is two shorter (1.88 Å) and two longer (1.90 Å) Cu–O bond length. O2- is bonded to two equivalent Eu3+ and two equivalent Cu+2.50+ atoms to form a mixture of distorted corner and edge-sharing OEu2Cu2 tetrahedra.
