Which of the following pairs represents linkage isomers ?

[Pd(PPh₃)₂(NCS)₂] and [Pd(PPh₃)₂(SCN)₂]

[Co(NH₃)₅ NO₃] SO₄ and [Co (NH₃)₅(SO₄)]NO₃

[PtCl₂(NH₃)₄] Br₂ and [Pt Br₂ (NH₃)₄] Cl₂

[Cu (NH₃)₄] [Pt Cl₄] and [Pt (NH₃)₄ [CuCl₄]

Answer

$Pd(PPh3)2(NCS)2$ and $Pd(PPh3)2(SCN)2$

Explanation

SCN¯ ion can coordinate through the sulphur or nitrogen atom. Such possibilities give rise to linkage isomerism in coordination compounds.

M ¬ SCN thiocyanato or thiocyanato-S

M ¬ NCS isothiocyanato or thiocyanato-N
