CaCo2O4 crystallizes in the tetragonal I4_1/a space group. Ca(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Co(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to two equivalent Ca(1) and two equivalent Co(1) atoms to form a mixture of distorted edge and corner-sharing OCa2Co2 tetrahedra.
CaCo2O4 crystallizes in the tetragonal I4_1/a space group. Ca(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. There are four shorter (2.44 Å) and four longer (2.51 Å) Ca(1)-O(1) bond lengths. Co(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. There are two shorter (1.85 Å) and two longer (1.88 Å) Co(1)-O(1) bond lengths. O(1) is bonded to two equivalent Ca(1) and two equivalent Co(1) atoms to form a mixture of distorted edge and corner-sharing OCa2Co2 tetrahedra.
