Abstract

A new barium ruthenium oxyhydroxide Ba₄Ru₃O_10.2(OH)_1.8 crystallises under hydrothermal conditions at 200 °C: powder neutron diffraction data show it adopts an 8H hexagonal perovskite structure with a new stacking sequence, while high resolution electron microscopy reveals regions of ordered layers of vacant Ru sites, and magnetometry shows antiferromagnetism with T_N = 200(5) K.
