Crystal Structure of the Clathrate of 5,12-Dihydro-5,12-o-benzenonaphthacene-1,4-dione with Benzene (2:1)

Abstract

In the crystal of the title compound, the quinone fragment of the host (1) participates in weak D-A interactions with a neighboring naphthalene moiety of 1 and with the guest molecule via fairly short intermolecular face-to-face contacts. An intermolecular electrostatic interaction between a quinone-oxygen atom and a neighboring quinone ring is suggested by short O…C contacts. There exist severl C-H…O hydrogen bonds, one of which seems to contribute to the formation of a centrosymmetric dimer of 1.
