The crystal structure of new ternary compounds Al2R11Ge8(R=Y, Gd, Tb, Dy, Ho, Er) was studied using X-ray powder diffraction data by Rietveld method. Scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS) was used for sample composition examination. The compounds crystallized in the Ge10Ho11structure type (space group I4/mmm). The phase was not found in the systems with R=La, Ce, Pr and Nd. The lattice thermal expansion study of the Al2Er11Ge8compound was carried out using high-temperature powder X-ray diffraction technique from 293K to 743K, and the calculated lattice and volume thermal expansion coefficients were αa=0.88×10−5K−1, αc=1.22×10−5K−1, and αV=3.01×10−5K−1, respectively.
