Palladium zinc aluminium (2.28/10.37/0.35), Pd2.28(1)Zn10.37(1)Al0.35(1), represents the upper limit of Al substitution into the parent cubic γ-brass Pd2+xZn11−x. The structure can be described in terms of a 26-atom cluster consisting of an inner tetrahedron (IT), an outer tetrahedron (OT), an octahedron (OH) and a cuboctahedron (CO), with the substituted Al atoms partially occupying the IT (.3m) and CO (..m) sites.
