“…In IR spectrum of the precursor (Figure 2(a )), the band at 1607.72 cm –1 is related to the azomethine group (C=N) which has shifted to a lower frequency compared to the copper (II) complex of Schiff base ligand (H 2 L) (1630 cm –1 ) [ 57 ] due to the presence of cobalt and tin in the compound. In the IR spectrum of nanocomposite 3 (Figure 2(b )), a strong band was observed at around 571 cm –1 which can be assigned to the M–O bond (M = Cu, Co, and Sn) [ 57 , 62 ]. The C–H and C–O stretching vibrations due to graphene sheets appeared at 2925 and 1383 cm –1 , respectively [ 63 ].…”

In this work, Co-Sn-Cu oxides/graphene nanocomposite, 30-40 � 0.5 nm in size, was synthesized by solid-state microwave irradiation. This method presents several advantages such as operational simplicity, fast, low cost, safe and energy efficient, and suitability for production of high purity of nanoparticles. Other advantages of this method are there is no need for the use of solvent, fuel, and surfactant. Co-Sn-Cu oxides/graphene nanocomposites have been characterized by Fourier transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, vibrating sample magnetometer, energy-dispersive X-ray spectroscopy, and UV-Vis spectroscopy. The synthesized nanocomposites were used as novel highly efficient catalysts for the synthesis of 1,8-dioxo-octahydroxanthenes at room temperature. The catalysts are recoverable and can be reused for six runs without loss of their activity. Also, the obtained nanocomposites exhibited significant anticancer activity against breast cancer cells and they could induce apoptosis in cancer cells.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…[14][15][16][17][18][19][20][21] Salicylaldehyde, 2-aminophenol, and 2-aminobenzoic acid are common organic reagents and can be easily converted into Schiff bases by reactions with amines and aldehydes or ketones, respectively (Figure 1a). [22][23][24][25][26][27] The resulting potentially bidentate ligands are ideal for coordination with a large number of metal ions and complexes. [18,[28][29][30] Moreover, aryl groups are activated by the presence of the electron-donating oxygen and nitrogen atoms, enabling the generation of diverse aryl-substituted ligand derivatives.…”

Three organic hydroxy‐carboxylic acids separated by a semirigid aromatic diaza scaffold and carrying alkyl groups of different steric hindrance (H′HL1, cyclopropyl; H′HL2, cyclohexyl; H′HL3, adamantyl) were employed as pro‐ligands. Their reaction with suitable triorganotin precursors leads to 10 complexes of compositions: [Me3Sn(HL1)]n·0.5nC6H5CH3 1, [Et3Sn(HL1)]n 2, [nBu3Sn(HL1)]n 3, [Ph3Sn(HL1)]n 4, [Me3Sn(HL2)]2·2CH2Cl2 5, [Et3Sn(HL2)]2 6, {[nBu3Sn(HL2)][nBu3Sn(HL2)(H2O)]} 7, [Ph3Sn(HL2)]n·nC2H5OH 8, [nBu3Sn(HL3)]n 9, and [Ph3Sn(HL3)]n 10. The solid‐state structures of 1–10 were deduced from single‐crystal X‐ray diffraction studies along with two of the pro‐ligands: H′HL1 and H′HL2. In the solid state, four different extended structure types were observed. In compounds 1–3 with aliphatic substituents at the tin atoms and a small substituent at the ligand backbone (cyclopropyl), 1D coordination polymers based on carboxylate bridging were observed, whereas compounds 4 and 8–10 with large substituents attached to the metal and the ligand (cyclohexyl and adamantyl) were 1D coordination polymers based on heteroditopic binding of the ligands. Albeit having essentially the same ligand conformation, the compounds having smaller substituents at the tin atoms (5, R = Me; 6, R = Et) comprise 24‐membered macrocyclic ring structures. In 7, water molecules are coordinated to half the tin atoms, giving dinuclear fragments {[HL2][nBu3Sn][HL2][nBu3Sn(H2O)]}, which are linked through OwH···Osal hydrogen bonds into 1D hydrogen‐bonded tapes. In solution, the tin atoms in 1–10 are coordinated to a single monoanionic [HL1–3]− ligand molecule utilizing anisobidentate coordination with the carboxylate group, as revealed from 119Sn nuclear magnetic resonance spectral results. The antiproliferative activity of the tri‐n‐butyl and triphenyltin compounds 3, 4, and 7–10 was evaluated against the cervical cancer cells (HeLa) and normal kidney cells (HEK) using the 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide assay. Of these, the adamantyl‐substituted tin complexes 9 and 10 present increased activity with IC50 values of 0.51 ± 0.01 and 0.41 ± 0.03 (μM) and good selectivity. The cell death mechanism was identified as apoptosis based on dual staining with fluorescent dyes (Hoechst 33342/propidium iodide and acridine orange/ethidium bromide) and might be related to reactive oxygen species.
