【Abstract】 The complex (n C4H9)3SnO2CCH2R (R=3 indolyl) was prepared by reaction of (n C4H9)3SnCl with sodium 3 indolylacetate in benzene. It has been determined by IR、1H NMR、elemental analyses and X ray structural analyses. The crystals are monoclinic, space group P21/n, with a=13.1361(4), b=10.266(2), c=17.299(5)?, and β=98.48(3)°. In the crystal the tin atoms are rendered five coordinate in a trigonal bipyramidal structure by coordinating with 3 indolyacetate groups. The resulting structure is a linear polymer containing two different Sn-O bond lengths of 2.194(3) and 2.522(3)?.更多还原
