Help on GAMESS

 Hello all,
     I'm wondering if there is someone who can help me on GAMESS. I'm
 trying to
 run a test calculation on tetrahedral ZrF4, but when I enter with the
 geometry unique
 atoms, GAMESS gives me an octahedra! My question is simple: What's
 wrong?
 The input and the result I have is following below. I thank in advance
 any help you
 could give-me.
 INPUT:
  $CONTRL SCFTYP=UHF RUNTYP=OPTIMIZE ECP=SBK $END
  $CONTRL EXETYP=CHECK $END
  $DATA
  --  Geometria de equilibrio do ZrF4
  TD
 Zircon 40 0.0 0.0 0.0
  SBK
 Fluor   9 0.0 0.0 2.15
  N31  6
  $END
 OUTPUT:
