The structure described by BeIn3 crystallizes in the tetragonal I4/mmm space group. Be(1) is bonded in a distorted square co-planar geometry to four equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 8-coordinate geometry to four equivalent In(1) and four equivalent In(2) atoms. In the second In site, In(2) is bonded to four equivalent Be(1) and eight equivalent In(1) atoms to form a mixture of distorted edge, face, and corner-sharing InBe4In8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
