Figure 1 The molecular structure of title compaund, with the atom–numbering scheme. Displacement ellipsoids are drawn at the 30% probability level. H atoms are presented as a small spheres of arbitrary radius. The intramolecular hydrogen bond is depicted by a dashed line. Only the major occupancy component of the disordered diethylamino–group [—N1(C2H5)2] is shown. |
