Embodiment Construction

[0019] To synthesize the HL ligand, a mixture of n-BuSn(O)OH (0.030 g, 0.14 mmol), ligand HL (0.100 g, 0.14 mmol), toluene 30 mL, and ethanol 10 mL was placed in a Dean-Stark apparatus It was heated to reflux for 8 hours, and the water formed in the reaction was removed by azeotropic distillation. The solution was then distilled under reduced pressure to obtain a white solid. Recrystallization from chloroform / dichloromethane / toluene solution at room temperature gave colorless crystals with a yield of 53%.

[0020] The main infrared absorption peaks are: 3419 (s), 2972 ​​(m), 2875 (s), 1636 (m), 1459 (w), 1398 (m), 1298 (s), 1208 (m), 1103 (w ), 1019 (w), 918 (m), 873 (s), 731 (m), 622 (m), 586 (m), 540 (s), 499 (m), 444 (m).

Abstract

The invention discloses a paddle wheel-shaped tin oxygen cluster complex composed of drum-shaped Sn6O6 and carboxyl calixarene and a preparation method thereof, and belongs to the chemical technical field. The complex has the following chemical formula: [(BuSn)(mu3-O)(L)]6.6(toluene); n-BuSn(O)OH and an HL ligand with a mixture of toluene and ethanol are subjected to heating reflux for 8 hours in a Dean-Stark apparatus, water generated in the reaction is removed by azeotropic distillation, and then the solution is subjected to reduced pressure distillation to obtain a white solid; a mixed solution of chloroform, dichloromethane and toluene is recrystallized at the room temperature to obtain a colorless crystal, and the yield is 53%. The invention discloses an anticancer activity research of organotin oxygen clusters based on calix[4]arene for the first time. The synthetic method has the characteristics of strong repeatability, high yield, stable product performance and the like. The complex shows relatively good fluorescence properties.

Description

technical field [0001] The invention belongs to the technical field of chemistry and relates to a complex and a preparation method thereof. Background technique [0002] Due to the diversity of structures and the application of organic tin oxygen clusters in organic catalysis, antibacterial and anticancer activities (V.Chandrasekhar, K.Gopal, P.Thilagar, Acc. Chem. Res. 2007, 40 , 420; B. Gleeson, J. Claffey, D. Ertler, M. Hogan, H. Müller-Bunz, F. Paradisi, D. Wallis, M. Tacke, Polyhedron 2008, 27 , 3619) have received extensive attention. [0003] The structure of organotin oxide clusters can be realized by adjusting the structure of organic ligands. The introduction of oxygen-containing ligands into organotin oxide clusters greatly enriches the structural types of the clusters. These oxygen-containing ligands include phenylcarboxylic acids (D.Kovala-Demertzi, V.Dokorou, R.Kruszynski, J.Wiecek, T.J.Bartczak, M.A.Demertzis, Z. Anorg. Allg. Chem . 2005, 631 , 2481...
