NO 4 3−is the “smallest” tetrahedral oxoanion so far , as shown by X‐ray structure analysis of painstakingly group (240 d) single crystals of Na 3 NO 4 . The NO distances (139 pm) are shorter than expected ( ca. 150 pm); the shortening can only be due to polar interactions superimposed on the single bond. In this way, the bond lengths in PO 4 3− , SO 4 2− , or ClO 4 −could also be explained without invoking pd‐π bonding.
