    Description / Table of Contents: Crystal and Molecular Structures of two [24]Cyclophanes: [24](1,2,3,4)Cyclophane and [24](1,2,3,5)CyclophaneThe benzene rings of the two [24]cyclophanes [24](1,2,3,4)cyclophane (1) and [24](1,2,3,5)cyclophane (2) show a boat-like (1) and a sofa-like (2) distortion from planarity. Because of interring repulsion the central C—C bonds of the ethano groups are stretched to 1.561-1.593 Å.
    Notes: Die Bestimmung der Kristall- und Molekularstrukturen der beiden [24]Cyclophane [24](1,2,3,4)-Cyclophan (1) und [24](1,2,3,5)Cyclophan (2) ergaben für die Phenylringe eine wannenförmige bzw. sofaförmige Deformation. Die abstoßenden Wechselwirkungen zwischen den Phenylringen bewirken weiterhin eine Dehnung der zentralen C—C-Bindungen der Ethanogruppen auf 1.561-1.593 Å.

    Kristall- und Molekularstruktur des Antharachinonophans [2.0.0](1,4)Benzeno(1,8)anthrachinono(1,4)benzenophan (1983)

    Description / Table of Contents: Crystal and Molecular Structure of the Anthraquinonophane [2.0.0](1,4)Benzeno(1,8)anthraquinono(1,4)benzenophaneBoth phenylene rings in the [5.2]paracyclophane subunit of the anthraquinonophane [2.0.0](1,4)benzeno(1,8)anthraquinono(1,4)benzenophane (1) are tilted by 37.6°. They show a boat-like deformation. The carbonyl group pointing towards the interior of the molecule interacts with the paracyclophane system. From this a strong boat-like deformation of the quinone ring of the anthraquinone moiety results.
    Notes: Die beiden Phenylenringe in der [5.2]Paracyclophan-Untereinheit des [2.0.0](1,4)Benzeno(1,8)-anthrachinono(1,4)benzenophans (1) sind um 37.6° gegeneinander geneigt und wannenförmig deformiert. Die Wechselwirkungen der ins Molekülinnere zeigenden Carbonylgruppe mit dem Paracyclophan-System verursachen eine starke wannenförmige Deformation des Chinonringes in der Anthrachinon-Einheit.
