 Complax is a Python tool designed to position solvent molecules (provided as `.xyz` files) around a user-specified atom of another molecule, also supplied in `.xyz` format.  
 It was primarily developed for the microsolvation of small organic molecules, but it can also be applied to other molecular systems, for instance as a starting point for further modeling or optimization studies.
