Dear Kim, the short answer is yes.

However, it'd be helpful to know which keywords you are using.

In your route you might have specified some type of calculation without SCF energy.

I used Opt, DFT, and UB3LYP calculation modes with the LANLDZ or SDD basis set, but I can't obtain the total energy value for Sn4+. Calculations for other complexes based on Sn4+ are performing well. Why is it that only the energy value for Sn4+ is not being produced?

I appreciate your help :D

Thanks for the details.

It'd be better to see if the output is printing some error message.
