Abstract: The title compound, C40H16O4 or [C10H4O]4, is a planar tetra­meric cyclo­oligomer which crystallizes in the monoclinic space group P21/n. The compound is located on an inversion center with the asymmetric unit consisting of half of the mol­ecule. The compound displays an inter­esting packing structure, where the cyclo­oligomer displays both layered packing with respect to nearest neighbors and a rotation of adjacent planar rings that results in additional interactions. The geometric parameters of the compound agree well with those of comparable cyclo­oligomers, while the packing reveals some similarities and differences.

Formula: C40H16O4
