چکیده
The title compound, C(6)H(6)N(2)O(3)·H(2)O, crystallizes with two formula units in the asymmetric unit. The mol-ecules are essentially planar with the nitro groups twisted slightly out of the ring planes [maximum deviations from the ring plane of 0.13 (2) and 0.22 (2) Å in the two mol-ecules]. The respective O-N-C-C torsion angles are 6.0 (4) and 12.5 (4)°. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯O, C-H⋯O, O-H⋯O and O-H⋯N inter-actions into a three-dimensional network.

متن کامل4-Aminoquinaldine monohydrate polymorphism: Prediction and impurity aided discovery of a difficult to access stable form.
Crystal structure prediction studies indicated the existence of an unknown high density monohydrate structure (Hy1B°) as global energy minimum for 4-aminoquinaldine (4-AQ). We thus performed an interdisciplinary experimental and computational study elucidating the crystal structures, solid form inter-relationships, kinetic and thermodynamic stabilities of the stable anhydrate (AH I°), the kinet...

In the title compound, C(6)H(6)N(2)O(3)·C(8)H(8)O(4), the 2-amino-4-nitro-phenol (ANP) and 1-(2,4,6-trihy-droxy-phen-yl)ethanone (THA) mol-ecules are both nearly planar, with r.m.s. deviations of 0.0630 and 0.0313 Å, respectively. The angle between the least-squares planes of THA and ANP is 48.99 (2)°. In THA, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, ...
