Figure 5
The molecular conformations of compounds, (A), (B) and (C). In (A), there are two independent benzoates indicated as A (C1–C37) and A′ (C1′–C37′). Black dashed lines indicate the intramolecular C—H⋯O interactions. Purple dotted lines indicate intramolecular H⋯H short contacts. For clarity, only H atoms involved in these interactions are shown.
