RESUMO
The title compound, C(4)H(6)N(2)S(3), has two very similar mol-ecules per asymmetric unit. The nine non-H atoms in each mol-ecule are coplanar, both having comparable r.m.s. deviations of 0.002â Å. The main inter-est in the rather simple structure resides in a survey of very weak (in some cases, borderline) non-bonding inter-actions of various kinds, viz. Sâ¯S, C-Hâ¯π, π-π [centroid-centroid distance = 3.8958â (13)â Å] and C-Sâ¯π [3.7271â (11)â Å], which act as the major driving force for the arrangement of mol-ecules in the structure. The role of long, though highly directional, Sâ¯S contacts (d > 3.60â Å), and their relevance to the stability of the structure is discussed.
RESUMO
In the title compound, C(10)H(12)N(2)OS(2), the thione and S-methyl groups are syn. An intra-molecular bifurcated O-Hâ¯(S,N) hydrogen bond occurs.
RESUMO
In the title compound C(11)H(13)N(3)OS, the aromatic ring and the dihydro-pyrazole ring are oriented orthogonally with respect to each other, making a dihedral angle of 89.92â (9)°. An intra-molecular O-Hâ¯S hydrogen bond occurs. In the crystal, weak N-Hâ¯N and N-Hâ¯S hydrogen bonds link the mol-ecules into a columnar stack propagating along the b axis.
