The crystal structure of the new phase Er0.85Co4.31Si
was determined by single-crystal X-ray diffraction (46 unique reflections, R1 = 0.0378,
wR2 = 0.0697). The compound crystallizes in the TbCu7
structure type: space group P6/mmm, hP8-1.85, with lattice
parameters a = 4.8593(19), c = 3.9869(16) Å. A full
investigation of the crystal structure was also performed for the known phase
CoSi on single-crystal X-ray diffraction data (61 unique reflections, R1 =
0.0256, wR2 = 0.0548). CoSi crystallizes in the FeSi structure type:
space group P213, cP8, with lattice parameter a =
4.4500(5) Å.
