User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an organic cation that is phenothiazin-5-ium substituted by dimethylamino groups at positions 3 and 7 as well as a nitro group at position 4. The chloride salt is the histological dye 'methylene green'.
Assistant: This is a molecule that fits this description: CN(C)c1ccc2nc3ccc(=[N+](C)C)c([N+](=O)[O-])c-3sc2c1
