WebAnswer. This coordination complex is called tetraamminechloronitrito-N-cobalt (III). N comes before the O in the symbol for the nitrite ligand, so it is called nitrito-N. If an O came first, as in [CoCl (ONO) (NH 3) 4] +, the ligand would be called nitrito-O, yielding the name tetraamminechloronitrito-O-cobalt (III).
