Nitrito vs nitro

Postby WUng_1D » Sat Dec 07, 2019 11:48 pm

What is the difference between nitrito and nitro? Looking at Lavelle's ligand names sheet both of them are called nitrito using the new IUPAC name convention. Except one has a -kN suffix and the other has a -kO suffix. Overall how do I recognize the difference between the two even though they are the same molecule.

-kN means that the N atom is bonding to the central atom in the coordination complex, and -kO means that the O atom is bonding. In a formula, the bonded atom will be written closest to the central atom:
N is bonding: [metal(NO2)]
O is bonding: [metal(ONO)]
