Abstract

The title compound is monoclinic, space group P21/c with a 7.697(2), b 5.627(3), c 18.043(4) ? and b 98.65(2)? dc = 1.368 for Z = 2. Final R = 0.077 (Rw = 0.085) for 516 reflections. Atomic coordinates are given. The 2 benzene and 2 oxadiazole rings are coplanar. The bond lengths indicate that there is appreciable conjugation between the 2 oxadiazole rings and little conjugation between the benzene and oxadiazole rings. The intermol. contacts appear to be normal.

Key words: CRYSTAL STRUCTURE, X-RAY DIFFRACTION ANALYSIS, BENZENE P, LINKED RING COMPOUNDS, OXDIAZOLE P
