Ca2CrO5 crystallizes in the orthorhombic Ima2 space group. Ca(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Cr(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to four equivalent Ca(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ca(1) and one Cr(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Ca(1) and two equivalent Cr(1) atoms.
Ca2CrO5 crystallizes in the orthorhombic Ima2 space group. Ca(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There is one shorter (2.38 Å) and one longer (2.42 Å) Ca(1)-O(1) bond length. There is one shorter (2.40 Å) and one longer (2.53 Å) Ca(1)-O(2) bond length. There is one shorter (2.30 Å) and one longer (2.41 Å) Ca(1)-O(3) bond length. Cr(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(3) atoms.
