Due to the presence of ambidenate ligands coordination compounds show isomerism. Palladium complexes of the type `[Pd(C_(6)H_(5))_(2)(SCN)_(2)]` & `[Pd(C_(6H_(5))_(2)(NCS)_(2)]` are

Options

A. Linkage isomerism
B. coordination isomers
C. ionization isomers
D. geometrical isomers.

Answer

1

Explanation

The ligands having two different bonding sites are known as ambident ligands e.g., `NCS^(-), NO_(2)^(-)` etc.
Here, `NCS^(-)` has two binding sites at N and S.
Hence, `NCS^(-)` (thiocyanate) can bind to the metal ion in two ways.
`M larr NCS or M larr SNC`
Thus, coordination compounds containing `NCS^(-)` as a ligand can show linkage isomers.
Hence, correct choice is (1).
