title: rac-(4aR,8aR)-2,3-Diphenyl-4a,5,6,7,8,8a-hexa-hydro-quinoxaline.
abstract: The structure of the title racemic compound, C(20)H(20)N(2), shows close similarity to that of the enanti-omerically pure (4aR,8aR)-2,3-diphenyl-4a,5,6,7,8,8a-hexa-hydro-quinoxaline [Wang & Ye (2008 ▶). Acta Cryst. E64, o359-o359]. The similarity applies to the unit-cell parameters as well as to the packing of the constituent mol-ecules. Similar packing is conditioned by a lack of directed inter-molecular inter-actions such as hydrogen bonds in either structure.
