The complexes [Me2(Indo)SnOSn(Indo)Me2]2, (1) [Bu2(Indo)SnOSn(Indo)Bu2]2, (2), where Hindo is indomethacin, have been prepared and structurally characterized by means of 119Sn Mössbauer, vibrational, and NMR (1H and 13C) spectroscopy. The crystal structures of the complexes [Me2(Indo)SnOSn(Indo)Me2]2 · 2C4H8O2, 3 and 2 have been determined by X-ray crystallography. Each structure is centro-symmetric and features a central rhombus Sn2O2 unit with two additional tin atoms linked at the O atoms. Pairs of tin atoms are bridged by bidentate carboxylate ligands and by a monoatomic bridging oxygen. C–H→π, π→π, stacking interactions, inter and intramolecular hydrogen bonds stabilize the structures 2 and 3. Complexes 2 and 3 are self-assembled via π→π, C–H-π and stacking interactions.The complexes [Me2(Indo)SnOSn(Indo)Me2]2, (1) [Bu2(Indo)SnOSn(Indo)Bu2]2, (2), where Hindo is indomethacin, have been prepared and structurally characterized by means of 119Sn Mössbauer, vibrational, and NMR spectroscopy.
