Figure 3
The mFo − DFc electron-density difference maps at a ±4σ level of the quantum-refined structures with wA = 0.1 (positive, green; negative, red) and wA = 0.3 (positive, magenta; negative, cyan) of the structure with PDB code 3u7q. The PN state is shown in atomic colours, whereas the P2+ state is shown in pale cyan. |
