Average Sigma (C-C)
Where available, average estimated standard deviation (e.s.d) [standard uncertainty (s.u.)] of carbon-carbon bond lengths can be displayed for Cambridge Structural Database (CSD) structures.
The average estimated standard deviation (e.s.d.) provides a rough measure of precision and is quoted for most Cambridge Structural Database (CSD) entries. In certain entries, where no carbon-carbon e.s.ds are available, then the value may be derived from C-N, C-O, N-N, N-O, O-O bond-length e.s.d.s.
