| Abstract: | The compounds Li5(BN2)Se and Li5(BN2)Te were synthesized at 900 °C in a closed system utilizing weld shut niobium ampoules and obtained as white microcrystalline powders. Their crystal structures were solved and refined on the basis of single‐crystal X‐ray diffraction data with the space group I41md a = 6.3983(4) Å, c = 11.1072(9) Å for Li5(BN2)Se and a = 6.5878(3) Å, c = 11.4382(7) Å for Li5(BN2)Te]. The temperature dependent Li+ motion was investigated by 7Li MAS NMR spectroscopy. |
