A series of hypercoordinated monoorganotin dibromides formed by glycolic acid amides, [RSnBr2(OCH2C(O)NR′2)]2 (2a, R = Et, NR′2 = NMe2; 3a, R = n-Bu, NR′2 = NMe2; 4b, R = Ph, NR′2 = morpholin-4-yl), were obtained and investigated by X-ray analysis, multinuclear NMR spectroscopy in solutions (1H, 13C, 119Sn) and solid state (CP/MAS). It has been established that 2a, 3a and 4b in solid state are dimeric. For the solutions in coordinating solvents the slow monomer-dimer equilibrium has been observed. The structures of related solvated monomeric chlorides, RSnCl(DMSO)(OCH2C(O)NR′2), 5a·DMSO and 6a·DMSO, were also investigated by X-ray analysis.
