Three new diorganotin(IV) complexes, [Bu2Sn(O2SeC6H5)(2)](n) (1), [Bu2Sn(O2SeC6H4Me)(2)](n) (2), [Me2Sn(O2SeC6H4Bu)(2)](n) (3) have been synthesized by the reaction of benzeneseleninic acid, p-tolueneseleninic acid, and 4-tert-butylbenzeneseleninic acid with Me2SnCl2 or Bu2SnCl2 in the presence of sodium ethoxide in methanol at 50 degrees C. All of the complexes were characterized by elemental analysis, FT-IR, NMR (H-1, C-13 and Sn-119) spectroscopy and X-ray crystallography. X-ray diffraction studies of 1, 2, 3 show that the areneseleninate groups behave as double bridges between the tin atoms leading to polymeric chain structure with Sn2O4Se2 eight-membered ring. The organic groups bonded to the tin atoms are in trans-position in the resulting octahedral arrangement. (C) 2011 Elsevier B.V. All rights reserved.
