organic compounds
The title compound, C17H10F5N5O2, is described and compared with its 4-nitrophenyl isomer [Bustos, Sánchez, Schott, Alvarez-Thon & Fuentealba (2007). Acta Cryst. E63, o1138–o1139]. The title molecule presents its nitro group split into two rotationally disordered components, which in conjunction with the rotation of the `unclamped' rings constitute the main molecular differences. Packing is directed by a head-to-tail type `I' C—FF—C interaction, generating double-chain strips running along [100]. These substructures are interlinked by a variety of weak FF, OF, Fπ and Oπ interactions.
organic compounds
In the title compound, there are two independent molecules forming hydrogen- and π-bonded dimeric entities with a noticeable noncrystallographic C2 symmetry. Dimers are linked by medium-strength type-I C—FF—C interactions, forming elongated tetramers.
