Abstract

The complex, (H 2NCOCH 2CH 2-C,O)(L)) SnCl 3, (L = EtCONH 2-O), isolated from a reaction mixture containing hydrochloric acid, tin and acrylamide in Et 2O solution, undergoes ligand exchange reactions with sulfoxides (sulfoxide = dimethyl sulfoxide, tetramethylene sulfoxide, 2-phenyl-1,3-dithiane trans-1-oxide and 2-phenyl-1,3-dithiane trans-1-trans-3-dioxide) to give (H 2NCOCH 2CH 2-C,O)(sulfoxide-O)SnCl 3. The tin centres in all the complexes are hexa-coordinated with a fac-CCl 3O 2 donor set, in which the octahedral geometries are somewhat distorted due to variations in the Sn-halide bond lengths, exemplifying the trans effect, and the small bite angles of the chelating (2-amidoethyl-C,O) ligand. The 2-phenyl-1,3-dithiane-1,3-dioxide ligand acts only as a monodentate ligand in its complex. The supramolecular structures are dominated by intermolecular hydrogen bonds with the NH 2 groups as the donor species. Halide exchange between (H 2NCOCH 2CH 2-C,O)- (tetramethylene sulfoxide-O)SnCl 3 and bromide ion was shown to give the mixed halide complex (H 2NCOCH 2CH 2-C,O) (tetramethylene sulfoxide-O)SnCl 1.5Br 1.5).
