Figure 7. Line plot of the structure of Na20 and the running coordination number of each atom (represented by a different colored line) in the structure. (A) Stable structure predicted based on Murrell-Mottram potential[15]; (B) structure generated in this study; (C) structure-optimized version of (B). (A) and (B) are outlier atoms with shielding constants of 368.1 and 386.4 ppm, respectively.
