Synthesis and Structure Characterization of Some Triorganotin Esters of Heteroaromatic Carboxlic Acid and Crystal Structure of Triphenyltin Esters 5-Chloro-6-hydroxynicotinic Acid
Reactions of (R3Sn)20 (R=Ph,2-CIC6H4CH2,2-FC6H4CH2.4-CNC6H4CH2) with 5-chloro-6-hydroxynicotinic acid in l/2 stoichiometry yielded eight triorganotin compounds.These compounds have been characterized by elemental analysis,IR and NMR spectroscopy.The crystal structures of triphenyltin esters of 5-chloro-6-hydroxynicotinic acid were determined by single crystal X-ray diffraction.In the compound,the tin atoms are rendered five-coordinated in a trigonal bipyramidal structure by coordinating though the three phenyl carbon atoms and two oxygen atoms one from carboxylate and other from the phenolic hydroxide.The resulting structure is one-dimensional linear polymers through an interaction between the O atoms of phenolic hydroxide and tin atoms of an adjacent molecule.
