[{"from": "human", "value": "Generate a molecule based on this description. The molecule is the disodium salt of a nitrogen-free bisphosphonate analog of naturally occurring pyrophosphate. Clodronate binds to calcium and inhibits osteoclastic bone resorption and hydroxyapatite crystal formation and dissolution, resulting in a reduction of bone turnover. This agent may control malignancy-associated hypercalcemia, inhibit osteolytic bone metastasis and decrease pain."}, {"from": "gpt", "value": "[C][Branch1][=Branch2][P][=Branch1][C][=O][Branch1][C][O][O][Branch1][=Branch2][P][=Branch1][C][=O][Branch1][C][O][O][Branch1][C][Cl][Cl].[Na].[Na]"}]
