# Which of the following pairs represents linkage isomers :

$\begin{array}{1 1}(a)\;[CO(NH_3)_4][PtCl_4]\;and\;[Pt(NH_3)_4][COCl_4]\\(b)\;[Pd(PPh_3)_2(NCs_2)]\;and\;[Pd(PPh_3)_2(SCN)_2]\\(c)\;[CO(NH_3)_5NO_3]SO_4\;and\;[CO(NH_3)_5SO_4]NO_3\\(d)\;[PtCl_2(NH_3)_4]Br_2\;and\;[PtBr_2(NH_3)_4]Cl_2\end{array}$

$[Pd(PPh_3)_2(NCs_2)]\;and\;[Pd(PPh_3)_2(SCN)_2]$ represents linkage isomers
Hence (b) is the correct answer.
