Project description:The structures of three 3-methyl-1H-1,2,4-triazole-5-thione derivatives are reported. The structure of 4-amino-3-methyl-1H-1,2,4-triazole-5(4H)-thione, C3H6N4S, (I), has been redetermined with an improved model for the H atoms: the non-H atoms of (I) all lie on mirror planes in space group Pbcm, and the H atoms of the methyl group are disordered over two sets of reflection-related atomic sites having occupancy 0.5: two independent N-H⋯S hydrogen bonds link the mol-ecules of compound (I) into complex sheets. The non-H atoms in the mol-ecules of 4-[(E)-(3,4-di-meth-oxy-benzyl-idene)amino]-3-methyl-1H-1,2,4-tri-azol-5(4H)-thione, C12H14N4O2S, (II), despite lying in general positions are close to planar, with a dihedral angle between the two rings of 6.31 (10)°: the mol-ecules of compound (II) are linked by a three-centre N-H⋯(O)2 hydrogen bond into a C(10)C(11)[R 1 (2)(5)] chain of rings. A second polymorph of 4-[(E)-(5-bromo-2-hy-droxy-5-bromo-benzyl-idene)amino]-3-methyl-1H-1,2,4-triazole-5(4H)-thione, C10H9BrN4OS, (III), has been identified; the non-H atoms are nearly co-planar with a dihedral angle between the two rings of 1.9 (4)°. There is an intra-molecular O-H⋯N hydrogen bond and the mol-ecules are linked by N-H⋯S hydrogen bonds, forming centrosymmetric R 2 (2)(8) dimers. Comparisons are made with some related structures.

3-Methyl-4-[(E)-3-thien-ylmethyl-idene-amino]-1H-1,2,4-triazole-5(4H)-thione.

Project description:The asymmetric unit of the title compound, C(8)H(8)N(4)S(2), contains two crystallographically independent mol-ecules. The thio-phene ring of one mol-ecule is disordered over two positions with refined site occupancies of 0.6375?(19) and 0.3625?(19). One mol-ecule is almost planar and the other one is twisted, the dihedral angles between the thio-phene and triazole rings being 7.28?(7) and 48.9?(2)° [48.5?(4)° for the minor component], respectively. An intra-molecular C-H?S hydrogen bond stabilizes the mol-ecular conformation of the planar molecule. In the crystal, the two mol-ecules are inter-connected by N-H?S hydrogen bonds into dimers, which are further consolidated into chains along the b axis by C-H?N hydrogen bonds. Weak C-H?? and ?-? inter-actions [centroid-centroid distance = 3.5149?(7)?Å] are also observed.

4-[(E)-(4-Chloro-benzyl-idene)amino]-3-methyl-1H-1,2,4-triazole-5(4H)-thione.

Project description:In the title compound, C10H9ClN4S, the dihedral angle between the mean planes of the phenyl and 1H-1,2,4-triazole-5(4H)-thione rings is 25.3 (9)°.

3-Ethyl-4-[(E)-2-methyl-benzyl-idene-amino]-1H-1,2,4-triazole-5(4H)-thione.

Project description:Crystals of the title compound, C(12)H(14)N(4)S, were obtained from a condensation reaction of 4-amino-3-ethyl-1H-1,2,4-triazole-5(4H)-thione and 2-methyl-benzaldehyde. In the mol-ecular structure, there is a short N=C double bond [1.255 (2) Å], and the benzene and triazole rings are located on opposite sites of this double bond. The two rings are approximately parallel to each other, the dihedral angle being 1.75 (11)°. A partially overlapped arrangement is observed between the nearly parallel triazole and benzene rings of adjacent mol-ecules; the perpendicular distance of the centroid of the triazole ring from the benzene ring is 3.482 Å, indicating the existence of π-π stacking in the crystal structure.

Project description:In the title mol-ecule, C11H12N4S2, the dihedral angle between the triazole and benzene rings is 21.31?(5)°.

Project description:The title compound, C10H10N4OS, is nearly planar with the mean planes of the hy-droxy-benzyl and triazole rings inclined at an angle of only 3.2 (7)°.

A weak intra-molecular C-H⋯S inter-action and inter-molecular π-π inter-actions [centroid-centroid distance = 3.5990 (15) Å] are also observed.
