How can I tell Gaussian to read coordinates as Cartesian?

[Dan Zar]

Hello,

I have been I am trying to optimize a molecule (crowded) with the chemical formula C₆₀H₅₂O₁₈P₄S₄W₂.

The problem arises after 2 days, which means that the initial geometry was not a problem.

Thank you very much.

I certainly have no idea what you are talking about. Is this some specific program you are running? If you want an answer you will need to give more information about what you are doing and what the question is.
