Redetermination of the crystal structure of R 5Si4 (R = Pr, Nd) from single-crystal X-ray diffraction data.

ABSTRACT: The crystal structures of praseodymium silicide (5/4), Pr5Si4, and neodymium silicide (5/4), Nd5Si4, were redetermined using high-quality single-crystal X-ray diffraction data. The previous structure reports of Pr5Si4 were only based on powder X-ray diffraction data [Smith et al. (1967 ▸). Acta Cryst. 22 940-943; Yang et al. (2002b ▸). J. Alloys Compd. 339, 189-194; Yang et al., (2003 ▸). J. Alloys Compd. 263, 146-153]. On the other hand, the structure of Nd5Si4 has been determined from powder data [neutron; Cadogan et al., (2002 ▸). J. Phys. Condens. Matter, 14, 7191-7200] and X-ray [Smith et al. (1967 ▸). Acta Cryst. 22 940-943; Yang et al. (2002b ▸). J. Alloys Compd. 339, 189-194; Yang et al., (2003 ▸). J. Alloys Compd. 263, 146-153] and single-crystal data with isotropic atomic displac
