The material described by Er5La5Ge6 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded in a 6-coordinate geometry to one Ge(1), one Ge(3), two equivalent Ge(2), and two equivalent Ge(4) atoms. In the second Er site, Er(2) is bonded in a 5-coordinate geometry to one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are three inequivalent La sites. In the first La site, La(1) is bonded in a 5-coordinate geometry to one Ge(1), two equivalent Ge(2), and two equivalent Ge(4) atoms. In the second La site, La(2) is bonded in a 5-coordinate geometry to one Ge(3), two equivalent Ge(1), and two equivalent Ge(4) atoms. In the third La site, La(3) is bonded in a 5-coordinate geometry to one Ge(3), two equivalent Ge(2), and two equivalent Ge(4) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to one Er(2), four equivalent Er(1), two equivalent La(1), and two equivalent La(2) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Er(2), four equivalent Er(1), two equivalent La(1), and two equivalent La(3) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Er(2), four equivalent Er(1), one La(2), and two equivalent La(3) atoms. In the fourth Ge site, Ge(4) is bonded in a 9-coordinate geometry to four equivalent Er(1), one La(2), two equivalent La(1), and two equivalent La(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
