Quadruple perovskites Ba{sub 4}LnRu{sub 3}O{sub 12} (Ln=La, Nd, Sm-Gd, Dy-Lu) were prepared and their magnetic properties were investigated. They adopt the 12L-perovskite-type structure consisting of Ru{sub 3}O{sub 12} trimers and LnO{sub 6} octahedra. All of these compounds show an antiferromagnetic transition at 2.5-30 K. For Ba{sub 4}NdRu{sub 3}O{sub 12}, ferrimagnetic ordering has been observed at 11.5 K. The observed magnetic transition is due to the magnetic behavior of the Ru{sup 4.33+}{sub 3}O{sub 12} trimer with S=1/2 . Magnetic properties of Ba{sub 4}LnRu{sub 3}O{sub 12} were compared with those of triple perovskites Ba{sub 3}LnRu{sub 2}O{sub 9} and double perovskites Ba{sub 2}LnRuO{sub 6}. - Graphical abstract: Quadruple perovskites Ba{sub 4}LnRu{sub 3}O{sub 12} (Ln=La, Nd, Sm-Gd, Dy-Lu) were prepared.
