The activated cluster Os₃(CO)₁₀(CH₃CN)₂ (1) reacts readily with a number of carboxylated chalcones and benzaldehydes (2a−j) to afford products with the general formula Os₃(CO)₁₀(µ-H)(µ-O₂CR) (3a–j). The structures of all the novel clusters have been characterized by IR and ¹H NMR spectroscopy, as well as mass spectrometry and elemental analysis. Single-crystal X-ray diffraction analysis has also been carried out for one of the carboxylated chalcones and two of the derivatized clusters. The activity of some of the derivatized clusters against the ER+ breast carcinoma MCF-7 cancer cell line has also been evaluated.
