<p>Using the cif you sent, I get the following:<br>
</p>
<p>username@computername:~/wiendata/Li3Ni2SbO6$ ls<br>
Li3Ni2SbO6.cif<br>
username@computername:~/wiendata/Li3Ni2SbO6$ grep space_group
*.cif<br>
_space_group_name_H-M_alt '<font color="#ff0000">A
2/m</font>'<br>

_space_group_symop_operation_xyz<br>

Li3Ni2SbO6.struct -wo Li3Ni2SbO6.struct_sgroup -set-TOL=0.00001
failed<br>
</p>
<p>Now, if I open Li3Ni2SbO6.cif in VESTA [1], click Edit -> Edit
data -> Unit Cell. I see that the cif file is in the <font
color="#ff0000">A 2/m</font> (Unique axis c) setting, which is
the wrong setting for WIEN2k. I select the <font color="#0000ff">B
2/m <font color="#000000">(Unique axis c)</font></font>, click
OK, click File -> Export Data, and Save the new cif file.<br>
</p>
<p>Then, when I rerun with the new cif file, I get the following:</p>
<p>username@computername:~/wiendata/Li3Ni2SbO6$ ls<br>
Li3Ni2SbO6.cif<br>
username@computername:~/wiendata/Li3Ni2SbO6$ grep space_group
*.cif<br>
_space_group_name_H-M_alt '<font color="#0000ff">B
2/m</font>'<br>
_space_group_IT_number 12<br>
_space_group_symop_operation_xyz<br>
<br>
username@computername:~/wiendata/Li3Ni2SbO6$ x cif2struct<br>
F UUUUUU�?<br>
0.003u 0.007s 0:00.01 0.0% 0+0k 0+48io 0pf+0w<br>
username@computername:~/wiendata/Li3Ni2SbO6$ x sgroup<br>
0.000u 0.004s 0:00.00 0.0% 0+0k 0+8io 0pf+0w<br>
username@computername:~/wiendata/Li3Ni2SbO6$ grep "space group"
*.outputsgroup<br>
Number and name of space group: 12 (C 2/m) [unique axis c] cell
choice 2<br>
</p>
<p>As seen, above WIEN2k then correctly detects the <font
color="#0000ff">B 2/m</font> (or B 112/m [2]) setting also known
as "12 (C 2/m) [unique axis c] cell choice 2".<br>
