Pt2In3 crystallizes in the trigonal P-3m1 space group. Pt(1) is bonded in a body-centered cubic geometry to three equivalent In(1) and five equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 6-coordinate geometry to six equivalent Pt(1) atoms. In the second In site, In(2) is bonded in a 5-coordinate geometry to five equivalent Pt(1) atoms.
