The compound described by EuAuAl crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded in a 9-coordinate geometry to five equivalent Au(1) and four equivalent Al(1) atoms. Au(1) is bonded in a 9-coordinate geometry to five equivalent Eu(1) and four equivalent Al(1) atoms. Al(1) is bonded to four equivalent Eu(1) and four equivalent Au(1) atoms to form a mixture of distorted corner, edge, and face-sharing AlEu4Au4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
