In my humble opinion YOU have to decide wether your structure looks like what you want. I only can/will expand somewhat on my previous advice to look at case.outputnn and to compare structures in xcrysden: Since xcrysden is difficult about arrows, do this in colors: You have 4 purple marbles

It is a valid procedure to generate a unit cell that supports placing antiparallel spins on the two Ni sublattices containing Ni1 and Ni2 atoms. I cannot tell you wether the new structure is 'true' or not. Concerning the crystal structure you simply should check youerself with xcrysden (or

I don't know what your question is, but hope that a comment might help. Apparently you did not change size and shape of the unit cell (using a 1*1*1 supercell), so the lattice constants and angles are the same. However, you told sgroup that there is not one type of Ni in the unit cell but
