1,2-Bis(4-nitrobenzoyl)-3,4-bis(4-nitrophenyl)cyclobutane

Abstract

In the title compound, C30H20N4O10, a typical bonding pattern is observed for the cyclobutane ring, with an average bond length of 1.560 (3) Å and bond angles of around 90°. In the crystal structure, the relatively short distances between the centroids of the benzene rings of neighbouring molecules [3.865 (3) and 3.845 (3) Å] indicate the existence of π–π interactions.
