We present a band structure study of orbital polarization and ordering in the two-dimensional triangular-lattice transition metal compounds and . It is found that while in the degeneracy of orbitals is lifted due to the trigonal symmetry of the crystal and the strong on-site Coulomb interaction, in orbital degeneracy remains and orbital ordering corresponding to the trimerization of the two-dimensional lattice develops.
