Of the two possible racemates formed on the dimerization of [2.2]paracyclophane, the title compound C32H30 is the meso (RS/SR) isomer. It crystallizes in moniclinic system in space group P2-1/n with Z=4 and unit cell dimensions: a=13.7612(12), b= 11.2530(10), c=14.6974(12) A, beta=99.668(8)degree (at-100degree C). The conformation is described by interplanar angle between the linked rings, 48.67(8)degree. Some widened angles in the region of C4-C4' may indicate steric congestion.
