#"SiCl"_4# is tetrahedral.

Explanation:

The Lewis structure of #"SiCl"_4# is

Lewis structure

This is an #"AX"_4#-type molecule, with four #"Si-Cl"# bonds.

According to VSEPR theory, these bonds must be pointing towards the corners of a regular tetrahedron.

Tetrahedron

So #"SiCl"_4# has a tetrahedral shape.
