BaCrO4 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 12-coordinate geometry to three equivalent O(2), three equivalent O(3), and six equivalent O(1) atoms. Cr(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one Cr(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one Cr(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one Cr(1) atom.
BaCrO4 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 12-coordinate geometry to three equivalent O(2), three equivalent O(3), and six equivalent O(1) atoms. There is one shorter (2.75 Å) and two longer (3.31 Å) Ba(1)-O(2) bond lengths. There is one shorter (2.78 Å) and two longer (3.17 Å) Ba(1)-O(3) bond lengths. There are a spread of Ba(1)-O(1) bond distances ranging from 2.83-2.94 Å. Cr(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. The Cr(1)-O(2) bond length is 1.64 Å. The Cr(1)-O(3) bond length is 1.64 Å. Both Cr(1)-O(1) bond lengths are 1.65 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one Cr(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one Cr(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one Cr(1) atom.
