The compound described by EuIn4 crystallizes in the monoclinic C2/m space group. Eu(1) is bonded in a 13-coordinate geometry to two equivalent In(1), three equivalent In(4), four equivalent In(2), and four equivalent In(3) atoms. There are four inequivalent In sites. In the first In site, In(1) is bonded in a 7-coordinate geometry to two equivalent Eu(1), one In(1), one In(3), and three equivalent In(4) atoms. In the second In site, In(2) is bonded in a 8-coordinate geometry to four equivalent Eu(1), one In(4), and three equivalent In(3) atoms. In the third In site, In(3) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one In(1), one In(3), and three equivalent In(2) atoms. In the fourth In site, In(4) is bonded in a 7-coordinate geometry to three equivalent Eu(1), one In(2), and three equivalent In(1) atoms. is represented by the CIF file [CIF]
