YCrMnO5 crystallizes in the orthorhombic Pbam space group. Y(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(4) atoms. Cr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form CrO6 octahedra that share corners with four equivalent Mn(1)O5 square pyramids and edges with two equivalent Cr(1)O6 octahedra. Mn(1) is bonded to one O(1), two equivalent O(3), and two equivalent O(4) atoms to form MnO5 square pyramids that share corners with four equivalent Cr(1)O6 octahedra and  an edgeedge with one Mn(1)O5 square pyramid. The corner-sharing octahedral tilt angles range from 50-58°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Cr(1) and one Mn(1) atom. In the second O site, O(2) is bonded to two equivalent Y(1) and two equivalent Cr(1) atoms to form distorted OY2Cr2 trigonal pyramids that share corners with two equivalent O(2)Y2Cr2 trigonal pyramids, corners with four equivalent O(4)Y2MnCr trigonal pyramids,  an edgeedge with one O(2)Y2Cr2 trigonal pyramid, and edges with four equivalent O(4)Y2MnCr trigonal pyramids. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Y(1) and two equivalent Mn(1) atoms. In the fourth O site, O(4) is bonded to two equivalent Y(1), one Cr(1), and one Mn(1) atom to form distorted OY2MnCr trigonal pyramids that share corners with two equivalent O(2)Y2Cr2 trigonal pyramids, corners with six equivalent O(4)Y2MnCr trigonal pyramids,  an edgeedge with one O(4)Y2MnCr trigonal pyramid, and edges with two equivalent O(2)Y2Cr2 trigonal pyramids.
