Abstract(summary):

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.
