Syntheses, characterizations and crystal structures of triorganotin(IV) derivatives with 2-mercapto-4-quinazolinone
چکیده انگلیسی

The triorganotin(IV) derivatives of 2-mercapto-4-quinazolinone (HSqualone) of the type, R3SnL (R = Ph 1, CH32, PhCH23, p-F-PhCH24, o-F-PhCH25, n-Bu 6), were obtained by the reaction of the R3SnCl and HSqualone with 1:1 molar ratio in benzene. All complexes 1–6 were characterized by elemental analyses, IR, 1H and 13C NMR spectroscopy and the crystal structures of complexes 1–3 were also confirmed by X–ray crystallography. The structure analyses reveal that the tin atoms of complexes 1–3 are all distorted tetrahedral geometries. Furthermore, the dimeric structures in complexes 1–3 have also been found linked by intermolecular O–H⋯N or N–H⋯O hydrogen bonding interaction. Interestingly, the dimers of complexes 2 and 3 are further linked into one-dimensional chain through intermolecular C–H⋯S and C–H⋯O weak hydrogen bonding interactions, respectively.
