Determine what the d manifold looks like for co2+ in a tetrahedral environment if the σ salcs for the ligands are [a1, t2], while the π salcs are [e, t1, t2]. determine what the d manifold looks like for ni2+ in a square planar environment if the σ salcs for the ligands are [a1g, b1g, eu], while the π salcs are [a2g, b2g, a2u, b2u, eg, eu]
