Histogram of P—Namide (first entry, blue in the electronic version of the paper) and P—NC(O)NHP(O) (second entry, brown) bond distances in phosphoric triamides with C(O)NHP(O)[N]2 and C(O)NHP(O)[NH]2 fragments. The numbers of data found in each region are given above the column. Seven CSD refcodes with unusual values for P—Namide or P—NC(O)NHP(O) and/or with strong disorder have not been considered. |
