Abstract: Tribenzyltin 4-picolinate(1) and tributyltin 4-picolinate(2) were synthesized by the reaction of sodium 4 picolinate with the tribenzyltin chlorideor tributyltin chloride and were characterized by IR, 1H NMRand MS. Their crystal structures were determined by X-ray single crystal diffraction. The crystal 1 crystallizes in monoclinic, space group P21/n with a=0.96564(8) nm, b=1.64085(14) nm, c= 1.49403(13) nm, β =97.681(2)o, V=2.3460(3) nm3, Z=4, Dc=1.456 g/cm3, and crystal 2 in monoclinic, space group P2 1/c with a=0.96673(14) nm, b=2.3845(4) nm, c=0.97071(14) nm, β =112.463(3)o, V=2.0679(5) nm3, Z=4, Dc=1.324 g/cm3. In crystals 1 and 2, the tin atom rendered five coordinate in trigonal bipyramidal structure by bridging pyridine Natom and the resulted structures are one dimensional infinite chain polymer.
