Synthesis and Crystal Structure of the One-Dimensional Chain Tributyltin Compound Bridged by Pyridine-4-carboxylic Acid N-Oxide
Chinese Journal of Inorganic Chemistry, 2012Co-Authors: Gao ZhongAbstract:An organotin compound [Bu3Sn(OCOC5H4NO)]n has been synthesized by the reaction of Bistributyltin Oxide with pyridine-4-carboxylic acid N-Oxide(HOCOC5H4NO) in molar ratio of 1∶2 and characterized by elemental analysis,IR and 1H NMR.The crystal structure has been determined by X-ray single crystal diffraction.The crystal belongs to monoclinic space group C2/c,with a=2.002 8(9) nm,b=1.224 7(6) nm,c=1.913 6(12) nm,β=119.145(6)°,Z=8,V=4.166(4) nm3,Dc=1.365 g·cm-3,μ=1.239 mm-1,F(000)=1 760,R=0.052 9,wR=0.192 1,GOF =1.013.In the compound,tin atoms are five-coordinated distorted trigonal bipyramid configuration with bridging pyridine-4-carboxylic acid N-Oxide.A one-dimensional linear polymer is formed through an interaction between the central tin atom and two O atoms.One O atom is from N-O and the other is from carboxyl group of another ligand.The compound exhibits good thermal stability and high antitumor activity.CCDC: 821908.
