Where to find molecular geometry for Psi4?

In summary, Psi4 is a computational chemistry software package that allows for the calculation of molecular properties and behavior using quantum chemistry methods. To find the molecular geometry, users can run a geometry optimization calculation in Psi4. This software also has a built-in visualization tool for viewing the molecular geometry in 3D. Tutorials and resources for using Psi4 can be found online, including the official user manual and Psi4Education website. However, there are limitations to determining molecular geometry in Psi4, such as difficulty with large or complex molecules and potential variability based on method and basis set selection. Careful consideration and validation of results is important.

TL;DR Summary
I want to calculate for example an energy of benzene using Psi4. Where can I find its molecular geometry so that I can do so?
I suppose there is a database for that, but I can't find it. Could anyone send here a link?
