Using IUPAC norms, write the formulae for the following:
(a) Sodium dicyanidoaurate(I)
(b) Tetraamminechloridonitrito-N-platinum(IV) sulphate
(a) Sodium dicyanidoaurate(I)
(b) Tetraamminechloridonitrito-N-platinum(IV) sulphate
Answer: (a) Na[Au(CN)₂]. (b) [Pt(NH₃)₄Cl(NO₂)]SO₄.
Solution
(a) Au(+1) with two CN: complex charge −1 →
(b) Pt(+4) with 4 NH, one Cl, one N-bonded NO: sphere charge +4−1−1 = +2, balanced by SO →
(b) Pt(+4) with 4 NH, one Cl, one N-bonded NO: sphere charge +4−1−1 = +2, balanced by SO →
