2-Hydr-oxy-3-methoxy-benzoic acid monohydrate.

ABSTRACT: The asymmetric unit of the title compound, C(8)H(8)O(4)·H(2)O, contains two organic mol-ecules which are connected by the two water mol-ecules through O-H⋯O hydrogen bonds, forming an R(4) (4)(12) ring. Further O-H⋯O hydrogen bonds assemble these rings through R(6) (6)(18) rings, giving rise to infinite helical chains arranged around the b axis. These helical chains are assembled by offset π-π stacking inter-actions [centroid-centroid distance = 3.6432 (8) Å] between the aromatic rings of neigboring chains, forming a supra-molecular network.

2-Hydr-oxy-1-methoxy-anthraquinone monohydrate.

Project description:The title compound, C(15)H(10)O(4)·H(2)O, also known as alizarin 1-methyl ether monohydrate, was isolated from Morinda officinalis How. The anthraquinone ring system is almost planar, the dihedral angle between the two outer benzene rings being 3.07?(4)°. In the crystal structure, O-H?O hydrogen bonds link the organic mol-ecules and the water mol-ecules, forming a three-dimensional network.

(E)-4-Hydr-oxy-N'-(2-hydr-oxy-4-methoxy-benzyl-idene)benzohydrazide monohydrate.

Project description:The Schiff base mol-ecule of the title compound, C(15)H(14)N(2)O(4)·H(2)O, adopts a trans configuration with respect to the C=N double bond; the Schiff base itself is almost planar (r.m.s. deviation for all non-H atoms = 0.040 Å). The amido N atom is the hydrogen-bond donor to the water mol-ecule, which is the hydrogen-bond donor to the hydr-oxy groups of two neighboring mol-ecules. One of the hydroxyl groups acts as an intra-molecular and the other as an inter-molecular hydrogen-bond donor.

2-Hydr-oxy-N'-(2-hydr-oxy-4-methoxy-benzyl-idene)-3-methyl-benzohydrazide monohydrate.

Project description:In the title compound, C(16)H(16)N(2)O(4)·H(2)O, the dihedral angle between the two benzene rings is 12.4?(2)° and the mol-ecule adopts an E configuration with respect to the C=N bond. There are intra-molecular O-H?N and O-H?O hydrogen bonds in the hydrazone mol-ecule, which both generate S(6) rings. In the crystal structure, mol-ecules are linked by N-H?O and O-H?O hydrogen bonds, forming layers parallel to the ab plane. The crystal studied was a non-merohedral twin with a domain ratio of 0.887?(3):0.113?(3).

N'-(4-Hydr-oxy-3-methoxy-benzyl-idene)acetohydrazide monohydrate.

Project description:In the title compound, C(10)H(12)N(2)O(3)·H(2)O, the Schiff base mol-ecule is approximately planar [within 0.189?(1)?Å]. The inter-planar angle between the benzene and acetohydrazide planes is 8.50?(10)°. In the crystal, mol-ecules are linked into a three-dimensional network by strong and weak O-H?O and strong N-H?O hydrogen bonds. The hydr-oxy H atom deviates from the 4-hydr-oxy-3-methoxy-phenyl mean plane by 0.319?(2)?Å, probably due to the involvement of this H atom in the O-H?O hydrogen bond. The weak O-H?O hydrogen bond is involved in a bifurcated hydrogen bond with R(1) (2)(4) motif. A weak C-H?? inter-action is also present.
