A new [1,3]thiazolo[3,2-
b
][1,2,4]triazol-7-ium-based cationic surfactant was examined as a stabilizer in the “wet chemistry” synthesis of silver and gold nanoparticles (NPs). The synthesis of the new [1,3]thiazolo[3,2-
b
][1,2,4]triazol-7-ium cationic surfactant was performed via the reaction of proton-induced cyclization of 5-heptadecyl-4-methyl-3-methallylsulfanyl-1,2,4-triazole. The new heterocyclic surfactant was explored as a stabilizer in an efficient synthesis of silver and gold NPs from silver nitrate and tetrachloroauric acid. The structure of the new [1,3]thiazolo[3,2-
b
][1,2,4]triazol-7-ium surfactant was analyzed by Fourier transformed infrared spectroscopy, nuclear magnetic resonance (on
1
H and
13
C nucleus), and with density functional theory calculations at the PBE0/def2-SVP/def2-TZVP(Ag/Au) level of theory. The NPs’ solutions were characterized by UV–Vis spectroscopy. The electronic structure and stabilization ability of [1,3]thiazolo[3,2-
b
][1,2,4]triazol-7-ium cation were compared with the characteristics of cetylpyridinium. 2-Heptadecyl-3,6,6-trimethyl-5,6-dihydro-3
H
-[1,3]thiazolo[3,2-
b
][1,2,4]triazol-7-ium perchlorate can be used as a stabilizer to synthesize Ag–, Au–, and Ag–Au-NPs. Quantum chemical modeling clearly shows a preferable association of metal NP anions (Ag
