Flux growth of a new cobalt–zinc–tin ternary phase Co7+xZn3−xSn8 and its relationship to CoSn

The intermetallic compound Co7+xZn3−xSn8 (−0.2

Co7+xZn3−xSn8 forms from the reaction of cobalt in zinc/tin eutectic flux; it exhibits a Cmcm subcell or Pnma supercell depending on reactant stoichiometry.Figure optionsDownload as PowerPoint slideHighlights
► Co7+xZn3−xSn8 grows from reaction of cobalt in Zn/Sn eutectic flux.
► Varying Co in reaction stoichiometry yields Cmcm subcell or Pnma supercell structure.
► Co7+xZn3−xSn8 structural building blocks similar to those in CoSn binary phase.
► Co7+xZn3−xSn8 forms from reaction of CoSn in the Zn/Sn flux.
