5-Isopropyl-5-methyl-2-sulfanylideneimidazolidin-4-one
In the title compound, C7H12N2OS, the 2-sulfanylideneimidazolidin-4-one moiety is nearly planar, with a maximum deviation of 0.054 (2) Å. In the crystal, a pair of N-H⋯O hydrogen bonds and a pair of N-H⋯S hydrogen bonds each form a centrosymmetric ring with an R 2 (2)(8) graph-set motif. The enanti-omeric R and S mol-ecules are alternately linked into a tape along [1-10] via these pairs of hydr...
متن کامل(E)-2-Methyl-5-(thiophen-2-ylmethylidene)cyclopentan-1-one
The exocyclic C=C double-bond in the title compound, C(11)H(12)OS, has an E configuration. The methyl-bearing C atom in the cyclo-pentane ring is disordered over two positions with a site-occupation factor of 0.899 (8) for the major occupied site.

In the title compound, C(7)H(8)N(2)O(4)S, the nitro group is twisted by 9.61 (2)° relative to the benzene ring. In the crystal, mol-ecules are linked by N-H⋯O and N-H⋯(O,O) hydrogen bonds between the amino and sulfonyl groups, forming layers parallel to (001).
متن کامل4-(4-Bromophenylhydrazono)-1-(5-bromopyrimidin-2-yl)-3-methyl-2-pyrazolin-5-one
The asymmetric unit of the title compound, C(14)H(10)Br(2)N(6)O, contains two crystallographically independent mol-ecules. The pyrazole ring of one mol-ecule makes dihedral angles of 22.0 (3) and 3.5 (3)° with the pyrimidine and benzene rings, respectively; the corresponding values in the other mol-ecule are 9.2 (3) and 2.1 (3)°, respectively. The mol-ecules are linked by N-H⋯O, C-H⋯N and C-H⋯B...
متن کامل5-(2-Methyl-5-nitrophenyl)-1H-tetrazole
In the title compound, C(8)H(7)N(5)O(2), the benzene ring makes a dihedral angle of 45.7 (2)° with the tetra-zole ring. In the crystal structure, the mol-ecules are linked into a chain running along the a axis by N-H⋯N hydrogen bonds, and the chains are linked through π-π inter-actions between the tetra-zole rings [centroid-centroid distance = 3.450 (2) Å].
