Organotin compounds are a recurring motif in organometallic chemistry. The syntheses and characterization of new diorganotin compounds with α‐oxoglutaric acid isonicotinyl hydrazone are described, prepared compounds were characterized by elemental analysis, UV/Vis, 1H, and 13C NMR spectroscopy, and X‐ray diffraction. They both have a distorted pentagonal bipyramidal arrangement, with a heptacoordinated central tin atom. Compound 1 presents a centrosymmetric dinuclear framework. Interestingly, intermolecular O–H···N and O–H···O hydrogen bonds contribute to the two‐dimensional network. Compound 2 is a simple mononuclear compound, which exhibits a rare one‐dimensional chain constructed by intermolecular O–H···Cl and N–H···O hydrogen bonds.
