IUPAC names of two complexes
Short answer
(i) potassium amminepentachloroplatinate(IV), (ii) pentaamminesulfatocobalt(III) bromide.
Write the IUPAC name of the following co-ordination compounds. (i) K[PtCl₅(NH₃)] (ii) [Co(NH₃)₅SO₄]Br
(i) K[PtCl₅(NH₃)]: potassium amminepentachloroplatinate(IV) (x − 5 = −1, so x = +4) (ii) [Co(NH₃)₅SO₄]Br: pentaamminesulfatocobalt(III) bromide (the sulfate is inside the sphere; x + 0 − 2 = +1, so x = +3)
