Abstract
The crystal structures of the two title compounds each display the chair conformation of their piperidine rings. In 4,4′-bis[3-(pyrrolidin-1-yl)prop-1-yn-1-yl]-1,1′-biphenyl, the biphenyl rings are coplanar because the molecules sit on crystallographic centres of inversion. In 4,4′-bis{3-[(S)-2-methylpyrrolidin-1-yl]prop-1-yn-1-yl}-1,1′-biphenyl, the biphenyl ring system has a twisted conformation with a dihedral angle of 28.76 (11)°.
