Figure 2
Fobs–Fcalc electron-density maps (isosurface level 0.18 e Å−3). Positive and negative residual electron density shown respectively as green and red mesh. Top: after initial structure refinement as ethyl ester 3. Bottom: after refinement as solid solution of ethyl (3) and d3-methyl ester (4). The pictures were generated with ShelXle (Hübschle et al., 2011  ). |
