Description
The crystal structures of Nb3(Al0.84Nb0.16) and Nb3(Al0.84Nb0.16)2H2.52 have been refined from neutron powder diffraction data using the Rietveld method. Nb3(Al0.84Nb0.16) crystallizes in the cubic Cr3Si-type structure, space group Pm anti 3n, with the unit cell parameter a=5.1907(1) A, Z=2. The dissolved deuterium atoms in Nb3(Al0.84Nb0.16)2H2.52 occupy three different tetrahedral sites and the unit cell parameter increases to a=5.3627(2) A. (orig.)
