{\left[ {S{F_6}} \right]^{2 - }}

is well known whereas

{\left[ {SiC{l_6}} \right]^{2 - }}

not. The main reason is/are:
I) Six large chloride ions cannot be accommodated around

S{i^{4 + }}

due to limitation of its size.
II) Interaction between lone pair of

C{l^ - }

ion and

S{i^{4 + }}

ion is not very strong.

View answer and explanation

Correct option: C

Both are correct

The correct answer is C because both statements are correct; the larger size of chloride ions and the limited size of Si4+ prevent six chloride ions from being accommodated, and the interaction between chloride and silicon is not strong enough.
