In this study, we report a novel hydrate former that acts as a structure II (sII) former and thermodynamic inhibitor. Thiazole is an aromatic five-ringed molecule with two heteroatoms. Thiazole forms an sII hydrate crystal with small CH4and CO2molecules. The Rietveld refinement result of sII (CH4+ thiazole) hydrate positions the thiazole off the center of 51264cages, and S and N atoms face O atoms at the apex of two pentagonal faces and one hexagonal face of the 51264cage, respectively. Considering the nearest N–O/S–O distances between N/S atoms of thiazole and O atoms in the 51264cage, both N and S atoms of thiazole exhibit guest–host interactions with water frameworks, such as O–H···N/O–H···S hydrogen bonds. Meanwhile, the thiazole molecule cannot form an sII hydrate with the C2H6molecule. It functions as a thermodynamic inhibitor of the structure I (sI) C2H6hydrate. The guest–host interaction of thiazole would not be so strong as that of tetrahydrofuran, which can form an sII hydrate without small molecules. Therefore, because the 51264cage is difficult to form by the combination of thiazole and C2H6molecules, the C2H6–thiazole–water system would form the sI C2H6hydrate.
