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]

Synthesis

[edit | edit source]

It is produced by coupling of two molecules of benzanthrone.[3][4][5][6]
