Synthesis and Crystal Structure of the One-dimensional Infinite Chain Organotin Complex [Ph3Sn(OCOC5H4NO)]n

A organotin complex [Ph3Sn(OCOC5H4NO)](n) has been synthesized by the reaction of tripnenyltin hydroxide with pyridine-3-carboxylic acid N-oxide in 1:1 ratio and characterized by elemental analysis, IR and H-1 NMR. The crystal structure has been determined by X-ray single crystal diffraction. The crystal belongs to monoclinic space group P2(1)/c, with a=1.378 29(7) nm, b = 1.635 85(8) nm, c= 1.881 01(9) nm, beta=96.048(2)degrees, Z=8, V=4.217 5(4) nm(3), D-c=1.537 Mg.m(-3), mu=1.236 mm(-1), F(000)=1 952, R=0.034 3, wR=0.1063, GOF=1.006. In the molecular structure of the title compound, the tin atoms are five-coordinated in a trigonal bipyramidal geometry. A one-dimensional linear polymer is formed through the interaction between the O atoms of N-O and tin atoms of the adjacent molecule.
