Abstract
Two dimethylglyoxime organotin compounds, bis(tri(2‑methyl‑2‑phenylpropyl)tin) dimethylglyoxime com‑ plex (C6H5C(CH3)2CH2)3Sn(ON= C(CH3)C(CH3) = NO)Sn(CH2C(CH3)2C6H5)3 (1) and di(benzyl)tin oxide, chlorine, butanedione oxime multinuclear complex [μ3‑O‑((C6H5CH2)2Sn)2(ON= C(CH3)C(CH3)= NOH)(O)Cl]2 (2), were syn‑ thesized. The compounds were characterized by elemental analysis, IR spectroscopy, NMR (1H, 13C, and 119Sn), ther‑ mogravimetric analysis, and single‑crystal X‑ray diffraction, and quantum chemical ab initio calculation was per‑ formed for their structure and in vitro anticancer activity were studied for the compounds. The results showed that complex 1 is a central symmetric molecule with double tin nuclei bridged by the ligand dimethylglyoxime, and the tin atoms are distorted tetrahedral configurations with four coordination. Complex 2 is a central symmetric polycy‑ clic polymerization structure of tetra‑tin nuclei bridged by oxygen atoms and dimethylglyoxime, and the tin atoms are five‑coordinated distorted triangular bipyramidal configuration and six‑coordinated distorted octahedral configu‑ ration, respectively. In addition, the complexes have stronger inhibitory activity on human liver cancer cells(HUH7), human lung cancer cells (A549), human epidermal cancer cells (A431), human colon cancer cells (HCT‑116), and breast cancer cells (MDA‑MB‑231). CCDC: 2234708, 1; 2234707, 2.
