Syntheses and characterization of triorganotin(IV) complexes of Schiff base derive from 4-amino-5-phenyl-4H-1,2,4-triazole-3-thiol and 5-amino-1,3,4-thiadiazole-2-thiol with p-phthalaldehyde |

Abstract: | Eight triorganotin complexes of the types (R3Sn)2(C24H16N8S2)].Y (R = Ph, Y = 0 (1); R = PhCH2, Y = 2CH3OH (2); R = n-Bu, Y = 0 (3)), (R3Sn)2(C24H16N8S2)]n (R = Me (4)), (R3Sn)2(C12H6N6S4)] · Y (R = Ph, Y = CH2Cl2 (5); R = PhCH2, Y = 0 (6)) and (R3Sn)2(C12H6N6S4)] (R = Bu (7), R = Me (8)) have been obtained by H2L1 (H2L1 derived from 4-amino-5-phenyl-4H-1,2,4-triazole-3-thiol) and H2L2 (H2L2 derived from 5-amino-1,3,4-thiadiazole-2-thiol) with triorganotin chloride in the presence of sodium ethoxide. All the complexes were characterized by elemental, IR and NMR spectra analyses, except for complexes 1, 3, 6 and 8, other complexes were also characterized by X-ray diffraction analyses, which reveal that complexes 2 and 5 are dinuclear structures, complex 4 has a 2D network structure and complex 7 forms a macrocyclic structure linked by intermolecular N → Sn interactions. |
