IUPAC names of four complexes

Short answer

i) hexaaquairon(II) sulfate, ii) sodium trioxalatoaluminate(III), iii) potassium hexafluoroaluminate(III), iv) diamminechloronitrito-N-platinum(II).

Write IUPAC name of the following co-ordination compounds i) [Fe(H₂O)₆]SO₄ ii) Na₃[Al(C₂O₄)₃] iii) K₃[AlF₆] iv) [PtCl(NO₂)(NH₃)₂]

i) [Fe(H₂O)₆]SO₄: hexaaquairon(II) sulfate ii) Na₃[Al(C₂O₄)₃]: sodium trioxalatoaluminate(III) iii) K₃[AlF₆]: potassium hexafluoroaluminate(III) iv) [PtCl(NO₂)(NH₃)₂]: diamminechloronitrito-N-platinum(II) (also written diamminechloronitroplatinum(II))

Ligands are listed in alphabetical order (ammine, chloro, nitro), and the charge on Pt is +2 because Cl⁻ and NO₂⁻ together give −2 on a neutral complex.
