Abstract
The ternary borides MgNi2,5B2 and Li1,2Ni2,5B2 have been prepared and investigated by X-ray methods. They are isotypic and crystallize hexagonal in the space group P6222—D4 6-with the following constants : MgNi2.5B2 α = 4.887 ± 0.002 Å, c = 8.789 ± 0.004 Å; Li1.2Ni2.5B2 a = 4.842 ± 0.002 Å, c = 8.664 ± 0.004 A. The structure contains boron-pairs and can be derived from the CeCo3B2-type of structure.Keywords
