I checked the ICSD database: The 2nd Ni position is:

-1/6 -1/3 1/4  !!!   but you entered   (1/6, 1/3, 1/4)

You should enter   either exactly these data (structgen accepts neg.
coordinates and transforms them automatically) or
5/6 2/3 1/4  (adding 1 to x and y) or you can invert
everything (since there is inversion) and enter  1/6, 1/3, 3/4

But your positions are wrong.
