Abstract

By reacting the ternary acetylides K2PdC2 and Rb2PdC2 at 300 degrees C under inert conditions a complete solid solution KxRb2-xPdC2 with x = 0-2 was obtained, which was followed and confirmed by synchrotron powder diffraction data. This solid solution shows ideal Vegard behavior, as predicted by Hume-Rothery rules for Delta V < 15 % (Delta V = 9.2 % for K+/Rb+). According to the powder diffraction data the formation of the quaternary acetylides seems to occur via diffusion of the alkali metal ions, whereas the (1)(infinity)[Pd-0(C-2)(2/2)(2-)] chains remain unaffected during this reaction.
