Figure 3
Residual EDD maps for the [Cr(CH3CN)6]2+ cation in the plane of atoms Cr1, N1, and N3. Panel (a) was calculated from the model corresponding to the unconstrained refinements, (2), and panel (b) was calculated from the model corresponding to the refinements with the constrained multipolar parameters, (3). Red lines represent positive contours and blue lines represent negative contours. Contours are drawn at 0.1 e− Å−3 intervals. |
