You are given the following two complexes X and Y which are isomers of each other, X is Hg `[Co(SCN)_(4)]`. It is further given that 'spin only' magnetic moment of X is found to be 3.78 BM and that of Y is 1.73 B.M. Then which of the following is correct ?

A

Anion of X will be tetrahedral and that of Y will be square planar

B

Anion of X will be square planar but that of Y will be tetrahedral

C

Both the anions will be tetrahedral

D

Both the anions will be square planar

Text Solution
