OsPtB4 is Ullmanite-like structured and crystallizes in the trigonal R3m space group. Os(1) is bonded in a 6-coordinate geometry to three equivalent B(1) and three equivalent B(2) atoms. All Os(1)-B(1) bond lengths are 2.28 Å. All Os(1)-B(2) bond lengths are 2.50 Å. Pt(1) is bonded in a distorted trigonal non-coplanar geometry to one B(2) and three equivalent B(1) atoms. The Pt(1)-B(2) bond length is 1.88 Å. All Pt(1)-B(1) bond lengths are 0.89 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a single-bond geometry to one Os(1) and one Pt(1) atom. In the second B site, B(2) is bonded in a distorted single-bond geometry to three equivalent Os(1) and one Pt(1) atom.
