Abstract

The structure of a Ni-substituted Al13(Ru,Ni)4 phase was analyzed by single crystal X-ray diffraction. The present analysis revealed the distribution of Ni at five heavy metal sites of Ru/Ni(1), Ru/Ni(2), Ru/Ni(3), Ru/Ni(4) and Ru/Ni(5). The anisotropic contraction of the corresponding coordination polyhedra around heavy metal sites was also suggested together with a variation of lattice constants as a function of Ni content.
