The propynide RbC=CCH3 is prepared from the reaction of propyne with a
solution of the metal in liquid ammonia, and is characterised using m
ainly X-ray powder diffraction, the tetragonal cell constants being co
mpared with those of the lithium (extrapolated), sodium, potassium and
caesium analogues.
