Figure 1
The structure of mol­ecule A, C34H20O2, one of four independent mol­ecules (A, B, C, and D) in the unit cell, showing the atom-labeling scheme with 30% probability ellipsoids. H atoms are rendered as spheres of arbitrary radius. An inversion center (1 − x, 1 − y, 1 − z) at the centroid of the central quinone ring generates the complete mol­ecule from a C17H10O substructure.
