Y2Cr3O12 crystallizes in the orthorhombic Fddd space group. Y(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a tetrahedral geometry to four equivalent O(3) atoms. In the second Cr site, Cr(2) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to one Y(1) and one Cr(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Y(1) and one Cr(2) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Y(1) and one Cr(1) atom.
Y2Cr3O12 crystallizes in the orthorhombic Fddd space group. Y(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. Both Y(1)-O(1) bond lengths are 2.41 Å. Both Y(1)-O(3) bond lengths are 2.23 Å. There are two shorter (2.33 Å) and two longer (2.49 Å) Y(1)-O(2) bond lengths. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a tetrahedral geometry to four equivalent O(3) atoms. All Cr(1)-O(3) bond lengths are 1.64 Å. In the second Cr site, Cr(2) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Cr(2)-O(1) bond lengths are 1.62 Å. Both Cr(2)-O(2) bond lengths are 1.68 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to one Y(1) and one Cr(2) atom.
