Residual density plots based on data from (a) the first scan, i.e. 0.63 MGy, and from (b) the 12th scan, i.e. 7.56 MGy. Carbon is shown in grey, nitro­gen is shown in blue, oxygen is shown in red, hydrogen is shown in white and nickel is shown in dark blue/purple. Residual peaks are coloured brown and the numbered Q labels refer to a ranked peak height. Values for residuals in hydrogen positions are 0.48–0.63 e Å3 and 0.31–0.40 e Å3 for structures shown in (a) and (b), respectively.
