Molecular geometry. IV. Structure of 3,4,10,11-dibenzo-1,8-diazacyclotetradeca-1,3,8,10-tetraene, a compound containing a 14-membered ring

Abstract

The structure of the title compound, C20H22N2, has been determined for the purpose of elucidating the conformation of a large ring. 1098 three-dimensional intensities were measured on a Picker PDP 8/I diffractometer and the structure was refined to an R value of 0.65. The space group is P21/c with Z= 2 and a--5-02, b = 9.60, c--16.35 ,&, fl= 96"5 °. The structure was solved by the symbolic addition method.
