| Abstract: | A crystal structure study of nBu2Sn(O2CCH2SC6H5)2 reveals the compound to be monomeric with the tin atom situated on a crystallographic 2-fold axis in a skew-trapezoidal bipyramidal geometry. The basal plane is defined by two asymmetrically chelating carboxylate groups; SnO 2.134(4) and 2.559(5) Å and the nBuSnnBu angle is 140.7(2)°. The sulphur atoms do not participate in any significant interactions to the tin atom. Crystals are monoclinic with space group C2 and unit cell dimensions a 18.668(6), b 15.761(6), c 5.106(5) Å, β 117.55(5)°; Z = 2. The structure was refined by a full-matrix least-squares procedure to final R = 0.034 and Rw = 0.033 for 1294 reflections with I ≥ 2.5σ(I). |
