PtO crystallizes in the triclinic P1 space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a bent 150 degrees geometry to two equivalent O(2) atoms. There is one shorter (1.46 Å) and one longer (1.73 Å) Pt(1)-O(2) bond length. In the second Pt site, Pt(2) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. There is one shorter (2.39 Å) and one longer (2.57 Å) Pt(2)-O(1) bond length. There is one shorter (2.39 Å) and one longer (2.57 Å) Pt(2)-O(2) bond length. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Pt(2) and one O(2) atom. The O(1)-O(2) bond length is 1.55 Å. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Pt(1), two equivalent Pt(2), and one O(1) atom.
