User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is the citric acid salt of fentanyl, comprising equimolar amounts of citric acid and fentanyl. A mu-opioid receptor agonist, it is a potent opioid analgesic used in the management of labour pain, postoperative pain, and chronic intractable cancer pain. It is also widely used as the analgesic component of balanced anaesthesia. It has a role as a mu-opioid receptor agonist and an opioid analgesic. It contains a fentanyl.
Assistant: This is a molecule that fits your description: CCC(=O)N(c1ccccc1)C1CCN(CCc2ccccc2)CC1.O=C(O)CC(O)(CC(=O)O)C(=O)O
