How to create a 4H SiC structure?

Dear All,

I am a new user for LAMMPS. I would like to create a 4H SiC structure based on the diamond structure.

The figure in this ppt can be as an example.

The shown chemical bonds on the Si and C atoms are wrong by using ovito.

I feel something wrong in my lattice and create_atoms commands.

But, I have no idea to revise it.

Maybe it should be created by diamond command.

Anybody can help me?

Thank you very much.

Best Regards,
