The crystal structure described by SrCa(CuO2)2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. Ca(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to two equivalent Sr(1), two equivalent Ca(1), and two equivalent Cu(1) atoms to form a mixture of face, corner, and edge-sharing OSr2Ca2Cu2 octahedra. The corner-sharing octahedral tilt angles range from 0-65°. is represented by the CIF file [CIF]
