Trinuclear Manganese(II) Complex Based on Diisopropyl(pyridin-2-ylmethyl)phosphine Oxide

A new trinuclear manganese(II) carboxylate complex [Mn3L2(OAc)6] (I), where L is diisopropyl(pyridin-2-ylmethyl)phosphine oxide, was synthesized. The composition of complex I was confirmed by mass spectrometry, IR spectroscopy, and elemental analysis. The crystal structure of the complex was determined by X-ray diffraction (CCDC no. 2447670). The luminescence and cytotoxicity of I were studied in relation to M-HeLa and HuTu80 cancer cell lines and Chang Liver normal cell line It was found that compound I exhibited high cytotoxicity against the HuTu80 cancer cells.
