The crystal structure described by K2PtP4O11Br crystallizes in the orthorhombic Fmm2 space group. There are two inequivalent K sites. In the first K site, K(1) 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. In the second K site, K(2) is bonded in a 5-coordinate geometry to one O(5), two equivalent O(3), and two equivalent O(4) atoms. Pt(1) is bonded in a 4-coordinate geometry to one Pt(1), two equivalent P(1), and one Br(1) atom. There are two inequivalent P sites. In the first P site, P(1) is bonded in a distorted trigonal non-coplanar geometry to one Pt(1), one O(1), one O(3), and one O(6) atom. In the second P site, P(2) is bonded to one O(2), one O(4), one O(5), and one O(7) atom to form edge-sharing PO4 tetrahedra. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one K(1) and one P(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one K(1) and one P(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one P(2) atom. In the fifth O site, O(5) is bonded in a distorted L-shaped geometry to one K(2) and two equivalent P(2) atoms. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. In the seventh O site, O(7) is bonded in an L-shaped geometry to two equivalent P(2) atoms. Br(1) is bonded in a single-bond geometry to one Pt(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
