%X The crystal structure of the quinone A, C15H14O6, derived from protoaphin-fb, has been determined by single-crystal X-ray diffraction at 295 K and refined by least squares to a residual of 0.051 for 758 ?observed? reflections. Crystals are monoclinic, P21, a 5.239(4), b 16.551(9), c 7.920(8) &#506;, &#946; 108.92(6)°, Z 2. The structure determination confirms that proposed chemically, including the chirality of all asymmetric centres in the molecule.
