Hi Accelrys Community,

I am relatively new to the field of materials modeling. I am trying to create a (101) surface of TiO2 anatase with thickness 2.0. I am able to create the surface and also rebuild the crystal with vacuum space of 25 Angstrom. But I want to create a slab with inversion symmetry. Is it doable in Materials Studio? I tried to redefine the crystal by adding inversion operator hence making the crystal with P-1 but it creates unusual bonding in the middle where the Ti atom bonds to very closely with another Ti atom and structure looks very weird. I am attaching the figure here that I generated when I asked Materials Studio to make it a P-1 structure.

My question in particular is: How to make a surface slab with inversion symmetry?

I apologize if this is a novice question and I tried to search for it in the community but I could not locate anyone asking/answering this kind of question.
