Abstract

Crystals of 1-chlorobenz[a]phenazine-7N-oxide, C16H9N2OCl, are orthorhombic,a =15·04,b = 3·91,c = 20·50 Å,Z = 4, space groupPna21. The crystal structure has been determined from two- and three-dimensional X-ray photographic data and refined by Fourier and least-squares methods toR = 0·095 for 715 observed reflexions. The molecule is slightly non-planar. Bond lengths and angles compare well with those of other molecules. Close molecular packing is given by layers of molecules parallel to (001) plane.
