Abstract
Abstract Eight new organotin(IV) complexes with 2,4,5-trifluoro-3-methoxybenzoic acid R n Sn(O 2 CC 6 HF 3 OCH 3 ) 4− n ( n = 3: R = Ph ( 1 ), PhCH 2 ( 2 ), Me ( 3 ), n -Bu ( 4 ); n = 2: R = Ph ( 5 ), PhCH 2 ( 6 ), Me ( 7 ), n -Bu ( 8 )) have been synthesized. All complexes were characterized by elemental, IR, 1 H and 13 C NMR spectra analyses, and the structures of complexes 1 , 3 , 7 and 8 were also determined by X-ray crystallography. The geometries at the tin atoms of 1 and 3 are five-coordinated and those of complexes 7 and 8 are six-coordinated. The structures of complexes 1 , 3 , 7 and 8 have been found to consist of 1D chains built up by intermolecular C–H⋯F weak hydrogen bonding. Intermolecular C–F⋯F weak non-hydrogen interactions in the crystal lattice of 3 link the molecules into a 2D network.
