There are two independent mol-ecules in the asymmetric unit of the title compound, C(13)H(13)NO(7)S, which have almost identical geometries. The thia-zine ring adopts a sofa conformation in both mol-ecules and the mol-ecular conformations are stabilized by intramolecular O-H⋯O hydrogen bonds. Inter-molecular C-H⋯O hydrogen bonds stabilize the crystal packing.

The asymmetric unit of the title compound, C(8)H(7)ClO(2), consists of two independent mol-ecules, with comparable geometries. Both mol-ecules are approximately planar (r.m.s. deviations = 0.040 and 0.064 Å for the 11 non-H atoms). In the crystal, mol-ecules are linked via inter-molecular O-H⋯O and C-H⋯O hydrogen bonds into chains two mol-ecules thick along (-101).

There are two independent mol-ecules in the asymmetric unit of the title compound, C(12)H(12)N(2), in which the pyrrole and benzene rings form dihedral angles of 72.37 (7) and 82.34 (8)°. The imino N-C bond lengths in the two mol-ecules are equal [1.286 (2) Å] and indicate C=N character. In the crystal, each mol-ecule forms a dimer with an inversion-related mol-ecule through a pair of classical...

The asymmetric unit of the title compound, C(58)H(96)N(2)O(4), contains two crystallographically independent mol-ecules. All cyclohexane rings are in chair conformations, while the furan ring is in an envelope conformation in one mol-ecule and a twist conformation in the other.

In the title mol-ecule, C(13)H(10)O(3), an intra-molecular O-H⋯O hydrogen bond influences the mol-ecular conformation, and the benzene and furan rings form a dihedral angle of 8.35 (7)°. Weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into sheets parallel to the bc plane.

In the title compound, C(21)H(15)F(3)N(2), the benzene ring bonded to the central C atom forms dihedral angles of 77.5 (7) and 89.0 (5)°, respectively, with the remaining two benzene rings. Weak inter-molecular C-H⋯F hydrogen bonds link the mol-ecules into chains propagated in [101]. The crystal packing exhibits weak π-π inter-actions as evidenced by relatively short distances between the centr...

The asymmetric unit of the the title compound, C(7)H(7)ClN(2)O, contains two mol-ecules in which the chloro-phenyl and the formic hydrazide units are almost planar (r.m.s. deviations of 0.0081 and 0.0100 Å, respectively, in one mol-ecule and 0.0069 and 0.0150 Å in the other) and are oriented with respect to each other at dihedral angles of 56.8 (2) and 56.9 (2)°. In the crystal, the mol-ecules ...

In the title compound, C(13)H(8)ClN(3)O(3)·C(3)H(7)NO, the benzimidazole and benzene rings make a dihedral angle of 0.63 (11)°. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. The solvent mol-ecule is hydrogen-bonded to the benzimidazole mol-ecule by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, generating an R(1) (2)(7) ring motif. In the crystal, the mol-ecules are arra...

The asymmetric unit of the title co-crystal, C12H9N5O·0.5C6H10O4, consists of one mol-ecule of N (6)-benzoyl-adenine (BA) and one half-mol-ecule of adipic acid (AA), the other half being generated by inversion symmetry. The dihedral angle between the adenine and phenyl ring planes is 26.71 (7)°. The N (6)-benzoyl-adenine mol-ecule crystallizes in the N(7)-H tautomeric form with three non-proton...
