Abstract

Crystals of the three novel oxorhutenates SrNiRu5O11 (a = 11.7374(2) Å, c = 13.2088(4) Å), SrZnRu5O11 (a = 11.7271(2) Å, c = 13.4246(4) Å), and Sr0.63(1)Ba0.37ZnRu5O11 (a = 11.7245(4) Å, 13.5268(4)) were obtained applying a flux-growth technique. A superstructure of the R-type ferrite crystal structure with doubled hexagonal a-axis (space group P63/m, Z = 8) originates from Ru—Ru pair formation within the kagome nets extending in (001). No indication for an intermixing of 3d metals at the Ru sites was observed.
