Abstract

The low-temperature boride Pd~5~B (Pd~16~B~3~) formscongruently from the corresponding interstitial solid solu-tion Pd(B) (Pearson-Parthé symbol cF(8-x), space group Fm__3̅__m) at 658 K. The structure of Pd~5~B has been investigated by X-ray powder diffraction yielding the following structural data: __I__4/mmm, __tI__2.38; unit cell parameters a = 0.28490(4) nm, c = 0.40038(9) nm, c/a = 1.405 < √2, with the occupation 2Pd (a) and 0.19 x 2B (b). The crystal chemical data of Pd~5~B and some other homeotypic interstitial compounds of transition metals have been compared.
