Y2CrMnO6 crystallizes in the monoclinic P2_1/c space group. Y(1) is bonded in a 8-coordinate geometry to two equivalent O(3), three equivalent O(1), and three equivalent O(2) atoms. Cr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CrO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-39°. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-39°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Y(1), one Cr(1), and one Mn(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Y(1), one Cr(1), and one Mn(1) atom. In the third O site, O(3) is bonded to two equivalent Y(1), one Cr(1), and one Mn(1) atom to form distorted corner-sharing OY2MnCr trigonal pyramids.
