Abstract

Abstract : Two chemical reagents in water at 200 °C yield a complex barium ruthenate with a new 8H perovskite stacking sequence. Abstract : A new barium ruthenium oxyhydroxide Ba4 Ru3 O10.2 (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.
