In2PbTe crystallizes in the monoclinic Cm space group. In(1) is bonded in a 10-coordinate geometry to three equivalent In(1), four equivalent Pb(1), and three equivalent Te(1) atoms. There is one shorter (3.38 Å) and two longer (3.51 Å) In(1)-In(1) bond lengths. There are a spread of In(1)-Pb(1) bond distances ranging from 3.36-3.65 Å. There are a spread of In(1)-Te(1) bond distances ranging from 3.36-3.53 Å. Pb(1) is bonded in a 12-coordinate geometry to eight equivalent In(1) and four equivalent Te(1) atoms. There are a spread of Pb(1)-Te(1) bond distances ranging from 3.38-3.64 Å. Te(1) is bonded in a 9-coordinate geometry to six equivalent In(1) and four equivalent Pb(1) atoms.
