Compound 4 was synthesized in a 92% yield and its 3D-structure confirmed by single-crystal X-ray diffraction. Hirshfeld surface analysis indicated that H…H, C-H…C, C-H…Cl and especially C-H…N hydrogen bond interactions are the primary contributors to the intermolecular stabilisation in the crystal. In order to explore the properties of 4, free from the influence of the crystal field, density functional theory (DFT) calculations were conducted. Results indicated that the DFT optimized geometry of 4 produced a conformer (4a) that is significantly different from the crystal structure. Further experiments confirmed that the crystal structure is not the absolute minimum conformation. This indicated that the crystal packing forces has significantly influen...

Meanwhile, alkylation of 2-(1-adamantyl)-1,3,4-oxadiazole-5-thiol 4 with 2-aminoethyl chlorides under the same conditions yielded only the S-alkyl derivatives 5. Interaction of 4 with primary or secondary amines and formaldehyde solution yielded the corresponding N-aminomethyl derivatives
