What is a MOL2 file?
A MOL2 file contains information about a molecule model saved in the SYBYL MOL2 format. It stores multiple records, such as MOLECULE, ATOM, BOND, SUBSTRUCTURE, and SET, along with 3D coordinates specifying the structure of atoms within a protein or other chemical compound. MOL2 files are similar to .MOL files.
You can open MOL2 files using various molecule visualization programs, such as IQmol and Avogadro. MOL2 files may also be opened using a text editor since they are saved in plain text.
