Syntheses,characterizations and crystal structures of triorganotin(IV) complexes with amine derivatives of 6-amino-1,3,5-triazine-2,4-dithiol

Four new triorganotin(IV) complexes: Me₃SnL¹SnMe₃ (1), Ph₃SnL¹SnPh₃ (2), Me₃SnL²] _n (3), Ph₃SnL²SnPh₃ (4) have been synthesized from 6-anilino-1,3,5-triazine-2,4-dithiol (L¹H₂) and 6-(dibutylamino)-1,3,5-triazine-2,4-dithiol (L²H₂). All were characterized by elemental analyses, IR and NMR spectra and X-ray diffraction analyses. Crystal structures show that 1, 2 and 4 are monomers with one ligand coordinated to two triorganotin moieties; complex 3 is a helical chain. Significant C–H ··· π, N–H ··· π interactions and intermolecular hydrogen bonds stabilize these structures.
