Usually the d-orbitals are displayed adapted to octahedral symmetry. But as I understand it, one could just as well picture degenerate representations of the same orbitals in other high symmetries. Does anyone have a link to a page containing pictures of the d-orbitals in the form adapted to tetrahedral symmetry? I reckon three of them should be "more combinable" with tetrahedrally coordinated ligands, since in ligand-field theory the d-orbitals split into one set of doubly and of triply degenerate orbitals, of which the triply degenerate ones form MOs with the (T1g I think) Td adapted orbitals of the ligands. It would be fun to see what the tetrahedral representations of the d-metals would look like (especially the two that won't combine).
