| Abstract: | New borides have been synthesized and their crystal structures have been determined using X-ray single-crystal methods, namely: Er0.917Ni4.09B, own structure type, space group P6/mmm, a=14.8399(3), c=6.9194(3) Å, RF=0.0545, and ErNi7B3, own structure type, space group I41/amd, a=7.6577(2), c=15.5798(5) Å, RF=0.0451. The relationship between these structures and the structure types of CeCo4B, Y0.915Ni4.12B and Sc4Ni29B10 has been discussed. |
