Some new diorganotin(IV) dichloride complexes of the general formula R
2SnCl2.L, where R = Me, Bu, Ph; L = OCH = CHCH = C- CH = N(O)C6H4X (X
= H, p - CH3, CH3O, CH3CO, F, Cl or Br) have been prepared and charact
erized by elemental analyses, and IR, H-1 and C-13 NMR spectroscopy. T
he spectral data show that the nitrone ligands coordinate with tin thr
ough the most active oxygen atom of the N-oxide to give penta-coordina
te tin complexes. An explanation for such observations is given.
