Figure 3
A section of the difference electron-density map for the present redetermined title structure, which shows the build up of the electron density between the atoms N and Nⁱ [symmetry code: (i) −x + 1, y, −z + $[{1\over 2}]$ ]. Positive and negative electron densities are indicated by continuous and dashed lines, respectively. The increment of electron density between the neighbouring contours is 0.02 e Å⁻³ (Petříček et al., 2014
