This is an AX4 -type molecule, with four Si-Cl bonds. According to VSEPR theory, these bonds must be pointing towards the corners of a regular tetrahedron. So SiCl4 has a tetrahedral shape. The molecule consists of a central Si atom, which has a coordination number of 4. Four chlorides (Cl) atoms can bond to Si. Therefore, the molecule has no net dipole moment.
