Question

Iupac name for Na2[CrF5NO]

Answer 1

The correct IUPAC name for Na2 [Fe(CN)5 NO] complex is

sodiumpentacyanidonitrosoniumferrate(II)

                            or

sodiumpentacyanidonitrosyliumferrate(II)

*I think it should be Na2 [Fe(CN)5 NO] not Na2[CrF5NO] as there is no complex with this formula
