Di‐ and tri‐organotin derivatives of N ‐benzoylglycylglycine (HBzGlyGly) were synthesized and characterized by infrared, 1 H, 13 C NMR and 119 Sn Mössbauer spectroscopy. Diorganotin derivatives appear to be dimer distannoxanes ([R 2 SnBzGlyGly] 2 O) 2 (R = CH 3 , n‐C 4 H 9 , n‐C 8 H 17 ) with a ladder‐type structure where tin atoms are five‐coordinated and N‐benzoylglycylglycine alternatively acts as a unidentate or bridging bidentate ligand through the carboxylate group. For triorganotin derivatives R 3 SnBzGlyGly (R= CH 3 , n‐C 4 H g ) we propose a polymeric structure where N ‐benzoylglycylglycine bridges planar SnC 3 units through the carboxylate group.
