I think you have typed in your structure wrong. A bond length of 1.4 Å between
two 3d-metals seems impossible. I could be wrong about this, but I checked
TiNi3 in the ICSD and you should note that the coordinates of the fourth atom
-1/6 -1/3 1/4
should be entered as
5/6 2/3 1/4
looking at your struct file you have done it wrong

 Best wishes Georg
