4-(2,7-Dimethyl-4-oxo-1,3-thia-zolo[4,5-d]pyridazin-5-yl)benzene-sulfonamide.

ABSTRACT: The thia-zole-pyridazine fused-ring system of the title compound, C(13)H(12)N(4)O(3)S(2), is approximately planar (r.m.s. deviation = 0.037?Å); the benzene ring connected to the fused-ring system through the N atom is twisted by 39.3?(1)°. The amine group uses an H atom to form a hydrogen bond to the ketonic O atom of an inversion-related mol-ecule to generate a dimer; adjacent dimers are linked by an N-H?O hydrogen bond to form a linear chain.

The thia-zole-pyridazine fused-ring system of the title compound, C(13)H(12)N(4)O(3)S(2), is approximately planar (r.m.s. deviation = 0.037 Å); the benzene ring connected to the fused-ring system through the N atom is twisted by 39.3 (1)°. The amine group uses an H atom to form a hydrogen bond to the ketonic O atom of an inversion-related mol-ecule to generate a dimer; adjacent dimers are linked by an N-H⋯O hydrogen bond to form a linear chain. ...[more]

Project description:The nine-membered fused-ring system of the title pyridazine derivative, C(13)H(12)N(4)O(4)S, is approximately planar (r.m.s. deviation 0.027 Å), and the benzene ring of the phenyl-sulfamide substituent is aligned at 43.5 (1)° to the fused-ring system. The amine group of the sulfonamide substituent forms an N-H⋯O hydrogen bond to the ketonic O atom of two neigboring mol-ecules to generate a chain running along the c axis.

Project description:The asymmetric unit of the title compound, C(11)H(12)N(2)O(4)S(2), contains two independent mol-ecules with similar dihedral angles of 76.7?(1) and 77.3?(1)° between the mean planes of the five- and six-membered rings. In both mol-ecules, the amino groups are involved in intra-molecular N-H?O hydrogen bonds. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds link mol-ecules into ribbons extended along the a axis.

Project description:In the title mol-ecule, C13H10N2S, the dihedral angle between the planes through the non-H atoms of the methylbenzene and thi-azo-lopyridine groups is 36.61 (5)°.

4-(5-Oxo-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)benzene-sulfonamide.

Project description:With respect to the aliphatic planar five-membered ring (r.m.s. deviation = 0.011?Å) of the title compound, C(15)H(13)N(3)O(2)S, the phenyl ring is aligned at 6.9?(1)° and the phenyl-ene ring at 2.4?(1)°, so that the three rings are nearly coplanar. The amino group has the N atom in a pyramidal geometry; the group is a hydrogen-bond donor to the sulfonyl O atom of one mol-ecule and to the ketonic O atom of another mol-ecule, resulting in the formation of a layer parallel to the bc plane.

In the crystal, mol-ecules form (100) sheets, although there are no specific directional inter-actions between them. The crystal stucture was refined as a two-component perfect twin.

Project description:In the crystal of the title compound, C(12)H(8)N(2)O(4)S, mol-ecules are linked into chains by a series of inter-molecular O-H?O, N-H?O and N-H?N hydrogen bonds.

The crystal structure indicates the presence of equimolar R and S enanti-omers in the crystal lattice, due to the presence of a chiral centre in the title compound.
