Abstract

Reactions of trialkyltin oxides with 2‐, 3‐, and 4‐pyridinecarboxylic acids in 1:1 stoichiometry yield 10 corressponding trialkyltin esters R~3~SnO~2~CC~5~H~4~N. All compounds are characterized by elemental analysis, IR, ^1^H, ^113^C, and ^119^Sn NMR. The crystal structure of tributyltin ester of 2‐pyridinecarboxylic acid is determined by single crystal X‐ray diffraction. In this compound, the tin atom is rendered five‐coordinate in a trigonal bipyramidal structure by coordinating with 2‐pyridinecarboxylate group. The resulting structure is a linear polymer containing SnO bonds (0.2278(5) and 0.2308(6) nm). © 2004 Wiley Periodicals, Inc.
