The compound was characterized using 1H NMR spectroscopy and mass spectrometry. Its exact conformational structure was determined via single crystal X-ray diffraction analysis. The compound has quite strained 1,2-alternate like structure because of its two high dihedral angled and rigid biphenyl parts in the crystal. The crystal includes the two isomers as two different 1,2-alternate like conformers, and the ratio of the two isomers is 78:22. %K Crystal Structure %K Metabiphenylcyclophane %K 1 %K 2-Alternate Conformers %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=70104
