Violanthrone, also known as dibenzanthrone, is an organic compound that serves as a vat dye and a precursor to other vat dyes. X-ray crystallography confirms that the molecule is planar with C2v symmetry. [1] Isomeric with violanthrone is isoviolanthrone, which has a centrosymmetric structure. [2]
It is produced by coupling of two molecules of benzanthrone. [3] [4] [5] [6]
