Pt4B3 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Pt4B3 clusters. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Pt(3,4) atom. The Pt(1)-Pt(3,4) bond length is 1.23 Å. In the second Pt site, Pt(2) is bonded in a single-bond geometry to one Pt(3,4) atom. The Pt(2)-Pt(3,4) bond length is 1.23 Å. In the third Pt site, Pt(3,4) is bonded in a distorted single-bond geometry to one Pt(2) and one B(3) atom. The Pt(3,4)-B(3) bond length is 0.53 Å. There are three inequivalent B sites. In the first B site, B(1) is bonded in a distorted linear geometry to one B(2) and one B(3) atom. The B(1)-B(2) bond length is 0.77 Å. The B(1)-B(3) bond length is 1.78 Å. In the second B site, B(2) is bonded in a distorted linear geometry to one Pt(3,4) and one B(1) atom. The B(2)-Pt(3,4) bond length is 0.53 Å. In the third B site, B(3) is bonded in a single-bond geometry to one Pt(3,4) and one B(1) atom.
