Pt5B crystallizes in the trigonal R3m space group. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted single-bond geometry to three equivalent Pt(3) and one B(1) atom. All Pt(1)-Pt(3) bond lengths are 1.67 Å. The Pt(1)-B(1) bond length is 1.93 Å. In the second Pt site, Pt(2) is bonded in a 3-coordinate geometry to three equivalent Pt(3) atoms. All Pt(2)-Pt(3) bond lengths are 1.38 Å. In the third Pt site, Pt(3) is bonded in a 5-coordinate geometry to one Pt(1), one Pt(2), two equivalent Pt(3), and one B(1) atom. Both Pt(3)-Pt(3) bond lengths are 0.80 Å. The Pt(3)-B(1) bond length is 2.66 Å. B(1) is bonded in a distorted tetrahedral geometry to one Pt(1) and three equivalent Pt(3) atoms.
