The material structure described by Er5Ni3Al3Ge4 crystallizes in the orthorhombic Pmmn space group. There are three inequivalent Er sites. In the first Er site, Er(1) is bonded in a 8-coordinate geometry to one Ni(2), three equivalent Ni(1), two equivalent Al(1), two equivalent Al(2), two equivalent Ge(1), and two equivalent Ge(2) atoms. In the second Er site, Er(2) is bonded in a 10-coordinate geometry to three equivalent Ni(1), two equivalent Al(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the third Er site, Er(3) is bonded in a 5-coordinate geometry to one Ni(2), two equivalent Al(2), four equivalent Al(1), and four equivalent Ge(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 10-coordinate geometry to three equivalent Er(1), three equivalent Er(2), one Ge(1), and three equivalent Ge(2) atoms. In the second Ni site, Ni(2) is bonded in a distorted q6 geometry to one Er(3), two equivalent Er(1), two equivalent Al(2), and four equivalent Al(1) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to two equivalent Er(1), two equivalent Er(2), two equivalent Er(3), two equivalent Ni(2), one Al(1), one Al(2), one Ge(1), and one Ge(2) atom to form a mixture of distorted face and edge-sharing AlEr6Al2Ni2Ge2 cuboctahedra. In the second Al site, Al(2) is bonded in a 12-coordinate geometry to two equivalent Er(3), four equivalent Er(1), two equivalent Ni(2), two equivalent Al(1), and two equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Er(1), two equivalent Er(2), two equivalent Er(3), one Ni(1), one Al(1), and one Al(2) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Er(1), three equivalent Er(2), three equivalent Ni(1), and one Al(1) atom. is represented by the CIF card [CIF]
