✦ Synopsis

The new phases (Ba 0.5 Sr 0.5 ) 7 Co 6 O 18 , Ba 8 Co 7 O 21 , and Ba 9 Co 8 O 12 have been shown by electron diffraction and highresolution electron microscopy to be three new members (n ‫؍‬ 5, n ‫؍‬ 6, and n ‫؍‬ 7) of the 2H hexagonal perovskite-related A n؉2 BB n O 3n؉3 homologous series. Their modulated structures are made up of chains, running along the c direction and separated by Ba(Sr) ions, containing a succession of one Co atom in prismatic trigonal sites and n Co atoms in octahedral coordination sharing faces. The strategy to synthesize different terms of this family is discussed in terms of the distance between AO 3 layers.

The (alpha =3, beta =2) member of the (A3ABO6) (A3B3O9) homologous series has been stabilised in the Sr-Rh-O system for a [Sr10(Sr0.5Rh1.5)TP(Rh6)Oh]O24 composition. The structural characterisation has been performed by powder X-ray and electron diffraction measurements and high-resolution electron
