[Wien] I have probleme with hydrogen

[youcef bouhadda]

Dear Pr Blah&, thank you for your replay
  do you mean by "meaningfull structure " that i should change my structure? I try to find in letteratur anthor strucure for ZrNiH and if someone have this structure i will be grateful.
  sincerly yours
  *
  *In metallic hydrides H is negatively charged and a quite
*"big" ion. Thus such small Me-H distances cannot be 
*correct.

*Use a meaningfull structure. (spacegroup, proper lattice parameter
*Ang/bohr !!), positions of H,...
