Figure 9
Comparison of the geometry of 2,2′-diethoxy α-truxillic acid molecules from (a) the solid-state reaction (48 h) and (b) from solution growth (Gopalan & Kulkarni, 2001

). The relative orientation of the carboxylic acid and ethoxy groups differ between the two structures. Values for the torsion angles t₁ and t₂ in the two structures are given in Table 3
