Figure 5
Electrostatic potential for (a) bpNO·F₄dIb and (b) bpNO·F₄dIb·bpNO modules extracted from the crystal. Contour maps are shown in the least-squares plane defined by the heavy atoms of the F₄dIb and bpNO molecules. Positive values (step = 0.1 e Å⁻¹) are denoted by solid contours; negative values (step = −0.05 e Å⁻¹) are denoted by dashed contours; wide dashed lines denote zero contours.
