K2PtO6 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 7-coordinate geometry to one O(3), two equivalent O(2), and four equivalent O(1) atoms. Pt(1) is bonded in a linear geometry to two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent K(1) and one O(2) atom to form a mixture of edge and corner-sharing OK4O trigonal bipyramids. In the second O site, O(2) is bonded in a 1-coordinate geometry to two equivalent K(1), one Pt(1), and one O(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one K(1) and one O(3) atom.
K2PtO6 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 7-coordinate geometry to one O(3), two equivalent O(2), and four equivalent O(1) atoms. The K(1)-O(3) bond length is 3.13 Å. There is one shorter (2.85 Å) and one longer (3.02 Å) K(1)-O(2) bond length. There are a spread of K(1)-O(1) bond distances ranging from 2.73-2.80 Å. Pt(1) is bonded in a linear geometry to two equivalent O(2) atoms. Both Pt(1)-O(2) bond lengths are 1.88 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent K(1) and one O(2) atom to form a mixture of edge and corner-sharing OK4O trigonal bipyramids. The O(1)-O(2) bond length is 1.40 Å. In the second O site, O(2) is bonded in a 1-coordinate geometry to two equivalent K(1), one Pt(1), and one O(1) atom.
