JEE MAIN - Chemistry (2009 - No. 15)
Which of the following pairs represents linkage isomers ?
[Pd (P Ph3)2 (NCS)2] and [Pd (P Ph3)2 (SCN)2]
[Co(NH3)5 NO3]SO4 and [Co(NH3)5 SO4]NO3
[Pt Cl2(NH3)4] Br2 and [Pt Br2(NH3)4] Cl2
[Cu (NH3)4] [Pt Cl4] and [Pt (NH3)4] [CuCl4]
Explicació
The $$SC{N^ - }$$ ion can coordinate through $$S$$ or $$N$$ atom giving rise to linkage isomerism
$$M \leftarrow SCN\,\,\,$$ thiocyanto
$$M \leftarrow NCS\,\,\,$$ isothiocyanato.
$$M \leftarrow SCN\,\,\,$$ thiocyanto
$$M \leftarrow NCS\,\,\,$$ isothiocyanato.
