摘要：

The title compound was Prepared as part of a study of polyphenylene derivatives obtained by arynic condensation in the presence of complex bases. X-ray analysis shows that the two benzocyclobutene moieties have an anti arrangement. The hydroxyl group and the H atoms are cis at each junction and trans for one junction with respect to the other. The two pseudosymmetrical parts Of the core of the molecule show the same geometry in spite of having different substitution. Previously observed deformations for the benzene moiety fused with the cyclobutene ring and lengthening of the cyclobutane Csp3-Csp3 bond are confirmed. The orientations of the formyl and hydroxyl groups are discussed.
