Two organotin heterocyclic carboxylate complexes di(o-bromobenzyl)tin bis(2-pyridinecarboxylate) (1) and tri(2-methyl-2-phenyl propyl)tin 3-indole butyrate (2) have been synthesized by a solvothermal method using methanol as solvent. The complexes were characterized by elemental analysis, IR spectroscopy, NMR (H-1, C-13, and Sn-119), X-ray diffraction, and thermogravimetric analysis. The crystal structures of the complexes were determined by X-ray single-crystal diffraction. The results show that the complexes have a single tin core structure, and the tin atoms are six-coordinate distorted oct...
