To draw the MO diagram for [CoCl6]4-, we need to first determine the point group of the molecule. The [CoCl6]4- anion has an octahedral geometry with the Co ion in the center and six Cl ions at the vertices. The point group of an octahedral molecule is Oh.

We can use the d-orbitals of the Co ion and the p-orbitals of the Cl ions to form molecular orbitals. The Co ion has five d-orbitals, which we label as dxy, dxz, dyz, dx2-y2, and dz2. The Cl ions contribute six p-orbitals, which we label as px, py, and pz for each Cl ion.

We can then use the symmetry-adapted linear combination (SALC) method to form linear combinations of the atomic orbitals that transform according to the irreducible representations of the point group. The SALCs for the d-orbitals and p-orbitals are shown below:
