In common usage, the prefix dipolar, dative or coordinate merely serves to indicate the origin of the electrons used in creating the bond. For example, F 3 B ← O(C 2 H 5) 2 ("boron trifluoride (diethyl) etherate") is prepared from BF 3 and :O(C 2 H 5) 2, as opposed to the radical species [•BF 3] – and [•O(C 2 H 5) 2] +.
Among English-speaking typographers the symbol may be called a "slashed O" [1] or "o with stroke". Although these names suggest it is a ligature or a diacritical variant of the letter o , it is considered a separate letter in Danish and Norwegian, and it is alphabetized after z — thus x , y , z , æ , ø , and å .

The C=O bond length in carbon dioxide is 116 pm. The C=O bonds in acyl halides have partial triple bond character and are consequently very short: 117 pm. Compounds with formal C≡O triple bonds do not exist except for carbon monoxide, which has a very short, strong bond (112.8 pm), and acylium ions, R–C≡O + (typically 110-112 pm).
