The crystal structures of three 3-methyl-1H-1,2,4-triazole-5-thio­nes, including a second polymorph of 4-[(E)-(5-bromo-2-hy­droxy­benzyl­idene)amino]-3-methyl-1H-1,2,4-triazole-5(4H)-thione and a redetermination of 4-amino-3-methyl-1H-1,2,4-triazole-5(4H)-thione

Figure 7
Part of the crystal structure of compound (II)

showing the formation of a hydrogen-bonded C(10)C(11)[R₁²(5) chain of rings running parallel to the [001] direction. For the sake of clarity, the H atoms bonded to C atoms have been omitted. The atoms marked with an asterisk (*), a hash (#) or a dollar sign ($) are at the symmetry positions ( $[{1\over 2}]$ − x, 1 − y, − $[{1\over 2}]$ + z), ( $[{1\over 2}]$ − x, 1 − y, $[{1\over 2}]$ + z) and (x, y, 1 + z) respectively.
