Dy₃RuO₇ with partial structural disorder

N. Ishizawa, T. Suwa and K. Tateishi

Abstract: The flux-grown single crystals of tridysprosium ruthenium heptaoxide, Dy₃RuO₇, have a noncentrosymmetric orthorhombic structure composed of infinite single chains of corner-linked RuO₆ octahedra embedded in a Dy₃O matrix. Partial disorder of Dy atoms was faintly observed. Two Dy atom sites out of the six crystallographically independent Dy sites split into two positions, which are separated by approximately 0.3-0.5 Å and have different coordination environments. The investigated crystal was an inversion twin.
