DLS and SAXS data of SaDHNA. (a) Autocorrelation function and corresponding mean radius distribution obtained by DLS, averaged over 300 s. (b) Averaged X-ray scattering intensities of SaDHNA (blue dots) in arbitrary units plotted against the scattering angle, i.e. momentum transfer values ranging from s = 0.05 to 2.4 nm−1. The red fit function corresponds to the SaDHNA ab initio model displayed in figure panel C, sharing a χ2-value of 1.54 with the corresponding experimental scattering data. (c) Superimposition of a single SaDHNA ab initio model calculated applying the program GASBOR and the tetramer of SaDHNA revealed by the crystal structure.
