The structure described by In4Pb crystallizes in the monoclinic C2/m space group. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 2-coordinate geometry to three equivalent In(2) and two equivalent Pb(1) atoms. In the second In site, In(2) is bonded to three equivalent In(1) and nine equivalent In(2) atoms to form a mixture of distorted edge, corner, and face-sharing InIn12 cuboctahedra. Pb(1) is bonded in a 4-coordinate geometry to four equivalent In(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
