Resumo

Abstract The 1 H NMR spectra in the pyridine proton region of six 2,6‐pyridinedicarboxylato‐(phenyl) (organo)tin(IV) compounds in DMSO‐d 6 solutions exhibit a pattern that, together with 13 C coupling data and 119 Sn chemical shifts, can be interpreted by a heptacoordinated pentagonal bipyramidal structure in which the tin atom is likely to be surrounded by two DMSO ligands in equatorial positions.
