Abstract
Tribenzyltin Ester of 4-Pyridinecarboxylic Acid has been synthesized by the reaction of 4-pyridinecarboxylic acid with Ph_3SnOH in 1∶1 molar fraction and characterized by elemental analysis,IR and 1H NMR.The crystal structure was determined by X-ray single crystal diffraction.The crystal belongs to Orthorhombic, space group P2_12_12_1,a=1.22176(19),b=1.4971(2),c= 2.4313(4)nm, Z=8,V=4.4471(12)nm3,Dc=1.464g/cm3,μ=1.172mm -1 ,F(000)=1968,R= 0.0437, wR=0.0674.In the crystal,the tin atoms are five-coordinated in trigonal bipyramidal structure by bridging pyridine N atoms,resulting in the chain organotin compound.
