KBrO4 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 10-coordinate geometry to one O(3), three equivalent O(2), and six equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to three equivalent K(1) and one Br(1) atom to form a mixture of distorted edge and corner-sharing OK3Br tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Br(1) atom. In the third O site, O(3) is bonded in a distorted linear geometry to one K(1) and one Br(1) atom. Br(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms.
KBrO4 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 10-coordinate geometry to one O(3), three equivalent O(2), and six equivalent O(1) atoms. The K(1)-O(3) bond length is 2.86 Å. There is one shorter (2.97 Å) and two longer (3.33 Å) K(1)-O(2) bond lengths. There are a spread of K(1)-O(1) bond distances ranging from 2.92-3.16 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded to three equivalent K(1) and one Br(1) atom to form a mixture of distorted edge and corner-sharing OK3Br tetrahedra. The O(1)-Br(1) bond length is 1.66 Å. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Br(1) atom. The O(2)-Br(1) bond length is 1.65 Å. In the third O site, O(3) is bonded in a distorted linear geometry to one K(1) and one Br(1) atom. The O(3)-Br(1) bond length is 1.64 Å. Br(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms.
