ResumoThe reaction of the 2,6-bis[(dimethylamino)methyl]phenyllithium with tin(IV) bromide affords, after recrystallisation from toluene on the air, the organotin(IV) compound [SnBr3{2,6-(Me2NCH2)2C6H3}(H2O)], 3, in which the N,C,N-ligand is bounded to Sn atom through the aryl carbon atom and one of the NMe2 groups only, while the second NMe2 group is protonated by hydrogen from the water molecule. The crystal structure analysis has shown dimeric structure of this compound, with unusually Sn–O–H–Br hydrogen bridges. This compound was characterised by NMR spectroscopy in solution and in the solid state and X-ray structure analysis.
