The crystal structure described by K2OsCOBr5 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Br(1), two equivalent Br(2), two equivalent Br(3), and two equivalent Br(4) atoms. Os(1) is bonded in an octahedral geometry to one C(1), one Br(1), one Br(3), one Br(4), and two equivalent Br(2) atoms. C(1) is bonded in a linear geometry to one Os(1) and one O(1) atom. O(1) is bonded in a single-bond geometry to one C(1) atom. There are four inequivalent Br sites. In the first Br site, Br(1) is bonded to four equivalent K(1) and one Os(1) atom to form a mixture of corner, edge, and face-sharing BrK4Os square pyramids. In the second Br site, Br(2) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Os(1) atom. In the third Br site, Br(3) is bonded to four equivalent K(1) and one Os(1) atom to form a mixture of distorted corner, edge, and face-sharing BrK4Os square pyramids. In the fourth Br site, Br(4) is bonded to four equivalent K(1) and one Os(1) atom to form a mixture of distorted corner, edge, and face-sharing BrK4Os square pyramids. is represented by the CIF card [CIF]
