YPtB crystallizes in the trigonal R3m space group. Y(1) is bonded in a single-bond geometry to six equivalent Pt(1) and one B(1) atom. There are three shorter (2.84 Å) and three longer (3.39 Å) Y(1)-Pt(1) bond lengths. The Y(1)-B(1) bond length is 0.97 Å. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Y(1) and three equivalent B(1) atoms. All Pt(1)-B(1) bond lengths are 2.54 Å. B(1) is bonded in a single-bond geometry to one Y(1) and three equivalent Pt(1) atoms.
