In the fourth Eu site, Eu(4) is bonded in a 4-coordinate geometry to one In(1), one In(3), and two equivalent In(2) atoms. In the fifth Eu site, Eu(5) is bonded in a 4-coordinate geometry to one In(3), one In(4), and two equivalent In(1) atoms. In the sixth Eu site, Eu(6) is bonded in a 4-coordinate geometry to one In(3), one In(4), and two equivalent In(2) atoms. In the seventh Eu site, Eu(7) is bonded in a distorted trigonal non-coplanar geometry to one In(1), one In(2), and one In(4) atom. In the eighth Eu site, Eu(8) is bonded in a distorted trigonal non-coplanar geometry to one In(1), one In(2), and one In(4) atom. There are four inequivalent In sites. In the first In site, In(1) is bonded in a 10-coordinate geometry to one Eu(2), one Eu(4), one Eu(7), one Eu(8), two equivalent Eu(1), two equivalent Eu(3), and two equivalent Eu(5) atoms. In the second In site, In(2) is bonded in a 10-coordinate geometry to one Eu(1), one Eu(3), one Eu(7), one Eu(8), two equivalent Eu(2), two equivalent Eu(4), and two equivalent Eu(6) atoms. In the third In site, In(3) is bonded in a body-centered cubic geometry to two equivalent Eu(2), two equivalent Eu(4), two equivalent Eu(5), and two equivalent Eu(6) atoms. In the fourth In site, In(4) is bonded in a distorted q6 geometry to two equivalent Eu(3), two equivalent Eu(5), two equivalent Eu(6), two equivalent Eu(7), and two equivalent Eu(8) atoms. is represented by the CIF card [CIF]
