Cyclic Trinuclear Diorganotin(IV) Complexes – The First Tin Compounds Bearing Oximehydroxamate Ligands: Synthesis, Structural Characterization and High In Vitro Cytotoxicity

The reactions between equimolar amounts of R 2 SnO (R = Me 1 , n Bu 2 ) and N ,2‐dihydroxy‐5‐[ N ‐hydroxyethanimidoyl]benzamide (H 2 L) under solvent reflux conditions (in toluene for 1 and methanol for 2 ) for ca. 4 h led to the formation of the trinuclear tin complexes [R 2 Sn(L)] 3 (R = Me 3 , n Bu 4 ) isolated as colourless crystalline solids in ca. 85 % yield, which were characterized by IR, 1 H, 13 C and 119 Sn NMR spectroscopy, elemental...
