早期的研究表明存在稀土锗化合物，其组成rgex接近3，结构未知。相应的镝化合物的中子衍射数据表明其化学计量为DyGe3。该化合物以一种与CrB结构类型相关的新型结构结晶。该结构为正交结构，由一个镝位点和三个锗位点组成。它可以被认为是由DyGe通过将由锗原子组成的三角棱镜板插入DyGe的CrB型单元电池而建立起来的。
Earlier investigations had indicated the presence of rare earth germanium compounds of a composition RGexwithxclose 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.
