Hello all, Can anybody help me for the position of the atoms in the lattice for Fe3N phase : P312 space group or 149 space group number ? I found the informations in ASM handbook for the other phase P63/mmc but I cannot find P312.

It might be very useful for any future reader of your cif file if you can paste the topas inp file in at least. It could either go as a comment or perhaps in [core cif]_refine_special_details(?). As impressive as Topas is, I didn't realise it is Turing complete. Gone are the days when most computer "inp"ut files were written in fortran ;-) One might hope that the (volunteer?) cif editors will be very happy to hear from you if you can suggest ways to improve the dictionary?
