Synthesis and characterization of trialkyltin esters of pyridinecarboxylic acids and crystal structure of [(n)Bu(3)Sn0(2)CC(5)H(4)N-2](infinity)

Reactions of trialkyltin oxides with 2, 3-, and 4-pyridinecarboxylic acids in 1:1 stoichlometry yield 10 corressponding trialkyltin esters R3SnO2CC5H4N. All compounds are characterized by elemental analysis, IR, H-1, C-113, and Sn-119 NMR. The crystal structure of tributyltin ester of 2-pyridinecarboxylic acid is determined by single crystal Xray 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). (C) 2004 Wiley Periodicals, Inc.
