|Title:||Synthesis and characterization of diorganotin esters of heteroaromatic carboxylic acid and crystal structure of nBU2Sn(2-PyCO2)2.H2O|
|Abstract:||Reactions of nBu2SnO with 2-furanyl, 2-furanvingl, 2-thiophenyl, 2-pyridinyl, 3-pyridinyl, 4-pyridinyl, 3-indolyl, 3-indolmethyl and 3-indolpropyl carboxylic acids in 1:2 stoichiometry yield complexes of the type nBu2(O2CR)2. These complexes, on treatment with nBu2SnCl2 afford the chloro complexes, nBu2Cl(O2CR). All the complexes have been characterized by elemental analysis, IR and 1H NMR spectral studies. The crystal structure of nBu2Sn(2-PyCO2)2.H2O has been determined by single crystal X-ray diffraction. The crystal belongs to rhombohedral with space group R-3c, a=15.807(3)Å, b=15.807(3)Å, c=15.807(3) Å, α=105.717(2)o,β=105.717(2)o, γ=105.717(2)°, Z=6, V=3397(8)Å3, Dc= 1.452g/cm3, μ=1.158mm-l , F(000)=1512, R1=0.0447, wR2=0.1038. In crystal, the tin atoms render seven-coordinate in a distorted pentagonal bipyramidal geometry. The two-dimensional network structure is formed by The H-bonding action between the free carboxyl groups and coordinated water molecule.|
