Abstract: Cyanein is a new antifungal antibiotic, isolated by Betina, et al. (CA 58, 11921d) from Penicillium cyaneum. By an x-ray procedure, the dimensions of the unit cell in the cyanein were a 19.075 ± 0.075, b 11.041 ± 0.018, and c 7.418 ± 0.021 A., the space group is P212121-D42. By assuming that the unit cell of cyanein contains 4 mols., the mol. wt. is 280.1 ± 1.6 which corresponds to an empirical formula C16H24O4.
