In the title mol-ecule, C(7)H(4)N(2)O(2)S(2), the nitro group is twisted by 5.5 (1)° from the plane of the attached benzene ring. In the crystal, N-H⋯S hydrogen bonds link pairs of mol-ecules into inversion dimers, which are linked by weak C-H⋯O inter-actions into sheets parallel to (101). The crystal packing exhibits short inter-molecular S⋯O contacts of 3.054 (4) Å and π-π inter-actions of 3....

In the title mol-ecule, C(12)H(15)NS(2), the 1,3-thia-zinane ring has a half-boat conformation; the C atom at position 5 deviates by 0.715 (2) Å from the mean plane (P) of the remaining five atoms. Plane P and the phenyl ring form a dihedral angle of 83.62 (3)°. In the crystal structure, weak inter-molecular C-H⋯S hydrogen bonds link mol-ecules related by translation along the axis a into chains.

Synthesis of 3,4-dihydropyrimidin-2(1H)-one and 3,4-dihydropyrimidin-2(1H)-thione derivatives from aldehydes, 1,3-dicarbonyl derivatives and urea or thiourea using granite and quartz as new, natural and reusable catalysts. Some of the 3,4-dihydropyrimidin-2(1H)-thione derivatives were used to prepare new heterocyclic compounds. The antimicrobial activity of selected examples of the synthesized ...

The mononuclear complex salt, [Cu(C3H5NS2)(C6H8N2S3)]NO3, contains a [C9H13CuN3S5](+) cation and an NO3 (-) anion. All of the non-H atoms of the cation lie on a mirror plane, as do the N and one O atom of the nitrate anion, such that the planes of the cation and anion are mutually orthogonal. The cationic complex adopts a slightly distorted trigonal-planar geometry about the Cu(I) cation. In th...
