Abstract
3 : 4-BENZPYRENE is one of the most potent carcinogenic compounds. It is the active cancer-producing agent in coal-tar and in the tars produced during the combustion of many organic materials. It crystallizes in two forms (a) monoclinic and (b) orthorhombic. The unit cells and space groups of both forms have already been determined1. (In this earlier work the compound was called 1 : 2-benzpyrene ; but the nomenclature was afterwards changed.) The monoclinic form has now been investigated in more detail.
