>In practice we tried different multiplicities for this system which is neutral. Making it positive is just to get a guess for the wave-function. As you proposed we can passivate the dangling cites but in fact the system is a monomer so we would like to study the electronic structure of the real system at first.

>>>We have used 3-21g and LANL2DZ basis sets for our case and we have followed the manual instructions to get convergence even we tried to get convergence for the positively charged case but our struggle with it was unsuccessful. In the following you can see some parts of the input and the complete input and output files
