Which of te following is/are correct for the water insoluble tellow coloured complex `K_(2)[PtCl_(6)]`?

Options

A. It is an innter orbital complex.
B. it is high spin complex.
C. its IUPAC name is potassium hexachloridoplatinum (IV).
D. it is homoleptic complex.

Answer

A, D

Explanation

For `4d//5d` metals all ligands act as strong field ligand (sfi) `Pt^(4+):5d^(6)`: pairing occurs `d^(2)sp^(3)` inner orbital los spin homoleptic (because only one type of ligand is present)
IUPAC name: potassium hexachloridoplatinate (IV) because coordination sphere is anionic.
