SADED maps of the oscillatory structure, I osc (left), the transient structure, I tr (centre), and the vibrationally hot structure, I hot (right). The top panels show the SADED maps of the entire PCN–224(Fe)–CO, and the middle and bottom panels show the SADED maps of the Zr 6 node and FeCO site, respectively. The red and blue colours show the negative and positive EDs, respectively, contoured at ±3 σ (0.16 e A − 3 for I osc , 0.09 e A − 3 for I tr and 0.43 e A − 3 for I hot ) in the top and middle panels and contoured at ±2 σ (0.1 e A − 3 for I osc , 0.06 e A − 3 for I tr and 0.28 e A − 3 for I hot ) in the bottom panels. Each σ represents the rms value calculated by taking the rms of the DED values for the corresponding SADED map.
