Four new triorganotin complexes of 3-amino-5-mercapto-1,2,4-triazole with the type of R3Sn(SC2N3HNH2-3) (R = Me, 1; n-Bu, 2; Ph, 3; PhCH2, 4) have been synthesized. All the complexes have been characterized by elemental analysis, IR, 1H NMR and 13C NMR spectra. Complexes 1, 3 and 4 have been characterized by X-ray crystallography analyses too. The geometry about Sn of complex 1 is distorted trigonal bipyramidal and the supramolecular structures of complex 1 has been found consist of channels built up by intermolecular N–H⋯N hydrogen bonding. The geometry of tin atoms in complexes 3 and 4 are distorted tetrahedron and 1D polymers connected by intermolecular N–H⋯N hydrogen bonding or N–H⋯N and N–H⋯S hydrogen bonding. Additionally, 1D polymer of complex 3 aggregated in 2D layer by intermolecular N–H⋯S hydrogen bonding.
