User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a member of the class of iron(3+) sulfides that has formula Fe2S3. A black powder, it decomposes at room temperature to give iron(2+) chloride, hydrogen sulfide, and sulfur.
Assistant: This is a molecule that fits your description: [Fe+3].[Fe+3].[S-2].[S-2].[S-2]
