Task: Please create a description for a molecule based on its representation.
SMILES: O=[Os](=O)(=O)=O
Constraint: Answer the question with full sentences.
Result: The molecule is an osmium coordination entity consisting of four oxygen atoms bound to a central osmium atom via covalent double bonds. It has a role as an oxidising agent, a poison, a fixative and a histological dye.
