The preparation, structure and spectral characteristics of intensely colored salts of 2-hydroxyimino-1,3-indandione with ammonia and amines are described. The crystallization of the salts takes place with a high yield. All the salts fluoresce in DMSO. MNDO calculations show that the formation of an anion from 2-hydroxyimino-1,3-indandione is associated with substantial alterations in the nitroso group.
