Zusammenfassung:
The crystal structure of the ternary Co2NiAl9 (Y-2 phase in the Co-Ni-Al
system) has been solved by single crystal methods. Despite the
expectation, the Y-2 structure cannot be considered as a possible
approximative structure for decagonal/icosahedra phases because of the
small size of the structural segments with pentagonal antiprisms and of
the absence of atoms with icosahedral atomic environment. An alternative
description using only transition metal polyhedrons is discussed.
