New layered Co oxides of nominal formula Sr 2 (Ln 0.8 Ca 0.2 ) Co 2 O 6 (Ln ‫؍‬ Sm, Eu, Gd, Tb, Dy, Ho, and Y) are reported. Single-phase polycrystalline samples were obtained at compositions Sr 2 Y 1؊x Ca x Co 2.5Ψ‰ O 6؊ (0.24x40.5; 04 40.24), Sr 2 Y 1؊x Ca x Co 3.4Ψ‰ 2 O 6Ψ‰ (0.24x40.5; 0.624 40.79),
