Synthesis, characterizations, and crystal structures of triorganotin(IV) derivatives with areneseleninic acids

摘要

Six new triorganotin(IV) complexes, [R_3Sn(O_2SeC _6H_4Cl)]_n (R = Me 1; Ph 2), [R _3Sn(O_2SeC_6H_4Me)]_n (R = Me 3; Ph 4), [R_3Sn(O_2SeC_6H_4Bu)] _n (R = Me 5; Ph 6) have been synthesized by the reaction of 4-chlorobenzeneseleninic acid, p-Tolueneseleninic acid, and 4-tert- butylbenzeneseleninic acid with triorganotin(IV) chloride in the presence of sodium ethoxide. All of the complexes were characterized by elemental analysis, FT-IR, NMR (~1H, ~(13)C, and ~(119)Sn) spectroscopy, and X-ray crystallography. Crystal structures show that all of the complexes exhibit 1D infinite chain structures which are generated by the bidentate oxygen atoms and the five-coordinated tin centers.
