  Crystal structure of the compound DyGe3

  摘要：

  Earlier investigations had indicated the presence of rare earth germanium compounds of a composition RGe(x) with x close to 3 of unknown structure. Neutron diffraction data obtained on the corresponding dysprosium compound show that the stoichiometry is DyGe3. This compound crystallizes in a novel type of structure related to the CrB structure type. The structure is orthorhombic and comprises one dysprosium site and three germanium sites. It can be thought to be built up from DyGe by inserting slabs of trigonal prisms consisting of germanium atoms into the CrB type unit cell of DyGe.

  The isothermal section of the phase diagram of the Dy-Fe-Ge ternary system at 773 K has been investigated mainly by X-ray powder diffraction (XRD), with the aid of differential thermal analysis (DTA) and optical microscopy (OM). Sixteen binary compounds have been confirmed. Five ternary compounds DyFe(4)Ge(2), DyFe(2)Ge(2), DyFe(6)Ge(6), Dy(117)Fe(52)Ge(112), and Dy(5)Fe(2)Ge(10) have been confirmed in this system at 773 K.
