Which of the following species is not stable?Due to the presence of d-orbitals in Si, Ge and Sn, they form species like $[SiF_6]^{2-}$, $[GeCl_6]^{2-}$ and $[Sn(OH)_6]^{2-}$. $[SiCl_6]^{2-}$ does not exist because six large chloride ions cannot be accommodated around $Si^{4+}$ due to its small size.
