HfPtIn2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfPtIn2 clusters. Hf(1) is bonded in a 3-coordinate geometry to one Pt(1) and two equivalent In(1) atoms. The Hf(1)-Pt(1) bond length is 0.81 Å. Both Hf(1)-In(1) bond lengths are 0.95 Å. Pt(1) is bonded in a 3-coordinate geometry to one Hf(1) and two equivalent In(1) atoms. Both Pt(1)-In(1) bond lengths are 0.95 Å. In(1) is bonded in a 3-coordinate geometry to one Hf(1), one Pt(1), and one In(1) atom. The In(1)-In(1) bond length is 0.81 Å.
