These tilts are in opposite senses and the mol-ecule possesses approximate mirror symmetry about a plane normal to the mol-ecule. In the crystal, mol-ecules form stacks in the [100] direction with adjacent mol-ecules related by translation, although the centroid-centroid separation of 4.136 (5) Å is probably too long to regard as a significant aromatic π-π stacking inter-action. An extremely weak C-H(midline ellipsis)O inter-action is also present. %G English %L hal-01208415 %U https://univ-rennes.hal.science/hal-01208415 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ ISCR %~ SCR_MACSE %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ UR1-SDLMJONCH %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ UR1-MMS %~ TEST2-HALCNRS
