3,8-Bis(4-chloro-phen-yl)-4,7-dimethyl-tricyclo-[4.2.2.0]deca-3,7-diene.

ABSTRACT: The title tricyclic diene, C(24)H(22)Cl(2), is the product of thermal ring-opening of a corresponding basketane (penta-cyclo-[4.4.0.0(2,5).0(3,8).0(4,7)]deca-ne) derivative. The cyclo-butene ring is planar to within 0.0032?(12)?Å and its geometry is normal. The two 4-chloro-phenyl groups are oriented in an approximately face-to-face conformation with a dihedral angle of 44.14?(6)° between them. The 4-chloro-phenyl group bonded to the cyclo-butene ring lies almost in the plane of the cyclo-butene ring, with a dihedral angle of 8.29?(17)° between the ring planes. The average intra-molecular C?C distance between the two C=C bonds is 2.92?Å. In the crystal structure, the mol-ecules are well separated with no close C-H?Cl or C-H?? inter-molecular inter-actions.
