The material structure described by K2Pt(OBr2)2 crystallizes in the orthorhombic Pbam space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent Br(1), and four equivalent Br(2) atoms. Pt(1) is bonded in a square co-planar geometry to two equivalent Br(1) and two equivalent Br(2) atoms. O(1) is bonded in a bent 120 degrees geometry to two equivalent K(1) atoms. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Pt(1) atom. In the second Br site, Br(2) is bonded to four equivalent K(1) and one Pt(1) atom to form a mixture of distorted corner and edge-sharing BrK4Pt trigonal bipyramids. is represented by the CIF file [CIF]
