YCrO4 is Zircon structured and crystallizes in the orthorhombic C222 space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(3) atoms. In the second Y site, Y(2) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(4) atoms. In the third Y site, Y(3) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are three inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a tetrahedral geometry to two equivalent O(3) and two equivalent O(4) atoms. In the second Cr site, Cr(2) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. In the third Cr site, Cr(3) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Y(1), one Y(3), and one Cr(3) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Y(2), one Y(3), and one Cr(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Y(1), one Y(3), and one Cr(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Y(2), one Y(3), and one Cr(1) atom.
