In the title adamantyl derivative, C(21)H(27)N(3)OS, the terminal meth-oxy-ethyl unit is disordered over two orientations with a refined site-occupancy ratio of 0.846 (6):0.154 (6). The 1,2,4-triazole ring is statistically planar [r.m.s. deviation = 0.002 (2) Å] and the phenyl substituent is almost perpendicular to its mean plane [dihedral angle = 83.57 (11)°]. No directional inter-molecular in...

The asymmetric unit of the title compound, C(10)H(8)N(6)·2H(2)O, comprises half the organic species, the mol-ecule being completed by inversion symmetry, and one water mol-ecule. The dihedral angle between the 1,2,4-triazole ring and the central benzene ring is 32.2 (2)°. The water mol-ecules form O-H⋯N hydrogen bonds with N-atom acceptors of the triazole rings. C-H⋯N hydrogen bonds are also ob...

In the title compound, C(11)H(11)FN(4)S, the dihedral angle between the 1,2,4-triazole ring and the benzene ring is 25.04 (12)° and an intra-moleuclar C-H⋯S inter-action leads to an S(6) ring. In the crystal, inversion dimers linked by pairs of N-H⋯S hydrogen bonds generate R(2) (2)(8) loops.

Triazoles with different substituent groups are found to possess diverse applications in the field of medicine and industry. A series of 4-(substituted ethanoyl)amino-3-mercapto-5-(4-nitro)phenyl-1,2,4-triazoles (NU-1 to NU-15) were synthesized as novel antimicrobial agents starting from 4-nitrobenzoic acid. The chemical structures of these newly synthesized compounds were elucidated by IR, 1H ...

The title compound, C19H23N3S, is a functionalized triazoline-3-thione derivative. The benzyl ring is almost normal to the planar 1,2,4-triazole ring (r.m.s. deviation = 0.007 Å) with a dihedral angle of 86.90 (7)°. In the crystal, molecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers that enclose R 2 (2)(8) loops. The crystal packing is further stabilized by weak C-H⋯...

In the title mol-ecule, C(24)H(21)ClN(4)OS(2), the central 1,2,4-triazole ring forms dihedral angles of 89.05 (9), 86.66 (9) and 82.70 (10)° with the chloro-substituted benzene ring, the methyl-sulfanyl-substituted benzene ring and the phenyl ring, respectively. In the crystal, mol-ecules are linked into sheets parallel to (100) by inter-molecular N-H⋯N and weak C-H⋯O hydrogen bonds.

BACKGROUND The objective of this study was to test the hypothesis that personality preference, which can be related to learning style, influences individual utilization of CAI applications developed specifically for the undergraduate medical curriculum. METHODS Personality preferences of students were obtained using the Myers-Briggs Type Indicator (MBTI) test. CAI utilization for individual s...

New heterocyclic derivatives of cyclopropane dicarboxylic acid comprising thiadiazole and 1,2,4-triazole moieties are reported. Reaction of 1,1-cyclopropane dicarboxylic acid (1) with thiosemicarbazide and phosphorous oxychloride resulted in 1,1-bis (2-amino-1,3,4-thiadiazol-5- yl)cyclopropane (2). Cyclopropane dicarboxylic acid thiosemicarbazide (6) was converted into 1,1-bis(3-thio-4H-1,2,4-t...

A new synthetic procedure for the efficient preparation of dinuclear ruthenium(II) polypyridyl complexes is reported. The compounds synthesized are [(bpy)2Ru(BPBT)Ru(bpy)2](PF6)2 and [(bpy)2Ru(BPZBT)Ru(bpy)2](PF6)2. (bpy = 2,2’bipyridine; H2BPBT = 5,5’-bis(pyridin-2-yl)-3,3’-bis(1,2,4-triazole); H2BPZBT = 5,5’bis(pyrazin-2-yl)-3,3’-bis(1,2,4-triazole). Electrochemical experiments show that the ...

In the title compound, C18H14N4O2, the triazole ring makes dihedral angles of 77.32 (8) and 75.56 (9)°, respectively, with the indoline residue and the terminal phenyl group. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds into tapes parallel to the b axis. The tapes are linked together by π-π inter-actions between triazole rings [inter--centroid distance = 3.4945 (9) Å].
