SiF subscript 6 superscript 2 minus end superscript comma space space space open square brackets GeCl subscript 6 close square brackets to the power of 2 minus end exponent space space and space open square brackets Sn left parenthesis OH right parenthesis subscript 6 close square brackets to the power of 2 minus end exponent are known to exist. Give possible reason.

Solution

It is because of the presence of d-orbital in Si, Ge and Sn. Due to this,they have the tendency to form complexes by accepting electron pairs from donor species.
 SiF subscript 4 space plus space 2 straight F to the power of minus space space rightwards arrow space space SiF subscript 6 superscript 2 minus end superscript GeCl subscript 4 space plus space 2 Cl to the power of minus space rightwards arrow space open square brackets GeCl subscript 6 close square brackets to the power of 2 minus end exponent Thus space SiF subscript 6 superscript 2 minus end superscript comma space space left square bracket GeCl subscript 6 right square bracket to the power of 2 minus end exponent space and space Sn left parenthesis OH right parenthesis subscript 6 right square bracket to the power of 2 minus end exponent space exists. where space the space hybridisation space of space the space central space atom space is space sp cubed straight d squared.
