摘要：
The crystal structure of NaBaLiNiF6 has been determined from X-ray single crystal data The crystal symmetry is cubic, space group Fm3m, with an unit-cell constant of a = 7.992(1)angstrom. Barium and sodium atoms occupy the A-sites (CN=12) with a small disordering of 10% between the two independent positions. The Li and Ni atoms are statistically disordered in the B-sites. These crystallographic results have been confirmed by magnetic susceptibility measurements and by NMR experiments on F-19, Na-23 and Li-9 nuclei.
