Crystal structures of 4-phenyl[2.2]paracyclophane (1), C22H20, monoclinic, P21/c, a = 14.7168(3), b = 7.8504(1), c = 15.1773(3) A, _ = 118.100(1), Z = 4; 4-(o-tolyl)[ 2.2]paracyclophane (3), C23H22, monoclinic, Cc, a = 11.354(1), b = 22.960(2), c = 7.7156(7)A, _ = 128.824(1), Z = 4; and 4-(2_,4_,6_-trimethylphenyl)[2.2]paracyclophane (6), C25H26, orthorhombic, Pbca, a = 12.892(4), b = 8.091(2), c = 35.895(9) A, _ = 90, Z = 8 have been determined. The interplanar angles between the aryl substituent and the cyclophane ring, to which they are bonded, are 38.0, 50.2 and 56.9_ in 1, 3 and 6, respectively. For 3, the methyl group of the substituent points away from the cyclophanyl cavity.
