Electrochemical Synthesis of Polymer Complexes with Selected Metals Based on 1-Vinyl-1,2,4-triazole

Zn(II) complexes of the composition [ZnLn2X2] and [ZnLn3(NO3)2] were synthesized, where n = 1, 2; X=Cl, Br, I; L1=2-aminothiadiazole-1,3,4, L2=2-amino-5-methylthiadiazole-1,3,4. The obtained complexes were studied by elemental analysis methods, IR and 1H NMR spectroscopy. The structure of the [ZnL22Br2] complex was determined by the RSA method (CIF file CCDC No. 2251742). The ligand molecules of 2-amino-5-R-thiadiazoles-1,3,4 (R = –H, –CH3) are coordinated monodentately by an endocyclic nitrogen atom located in the α-position to the amino group. The polyhedron of the central atom of halide complexes is a slightly distorted tetrahedron, in the coordination sphere of which two halide atoms and two endocyclic nitrogen atoms are located. During complexation in the spectrum of the solution of the [ZnL22Br2] complex, coordinated L2 ligands undergo amino-imine tautomerization into a heterocyclic amine with a nitrogen atom in a heterocycle. The polyhedron of the central atom for nitrate complexes is a slightly distorted trigonal bipyramide, in the coordination sphere of which three nitrogen atoms of ligands are located in the equatorial plane and two oxygen atoms of two nitrate anions in the axial position.
