(Z)-1-(2-Hy-droxy-eth-yl)-4-(2-meth-oxy-benzyl-idene)-2-methyl-1H-imidazol-5(4H)-one.

ABSTRACT: In the title compound, C14H16N2O3, an analog of the chromophore in green fluorescent protein, the meth-oxy-phenyl substituent and the imidazole N adopt a Z conformation with respect to the C=C bond. Aside from the hy-droxy-ethyl group, the mol-ecule is approximately planar, with the five- and six-membered ring planes forming a dihedral angle of 9.3?(1)°. An intra-molecular C-H?N contact occurs. In the crystal, O-H?N hydrogen bonds link the mol-ecules, forming chains along the b-axis direction. C-H?O hydrogen bonds are also observed.

Project description:In the title compound, C(17)H(14)N(2)O(2), the asymmetric unit comprises two mol-ecules that are comformationally similar [the dihedral angles between the phenyl rings in each are 46.35 (2) and 48.04 (3)°], with the conformation stabilized by intra-molecular O-H⋯N hydrogen bonds, which generate S(7) rings. In the crystal, inversion-related mol-ecules are linked by pairs of weak C-H⋯O hydrogen bonds, forming dimers with an R(2) (2)(16) graph-set motif. Weak inter-ring π-π stacking is observed in the structure, the shortest centroid-to-centroid distance being 3.7480 (13) Å.

2-[({2-[(2-Hy-droxy-5-meth-oxy-benzyl-idene)amino]-eth-yl}imino)-meth-yl]-4-meth-oxy-phenol.

Project description:The asymmetric unit of the title compound, C(18)H(20)N(2)O(4), contains one-half mol-ecule with an inversion center located at the centroid of the mol-ecule. In the crystal, mol-ecules are linked by C-H?? inter-actions, forming layers parallel to (101). An intra-molecular O-H?N hydrogen bond also occurs.

2-Eth-oxy-6-({2-[(3-eth-oxy-2-hy-droxy-benzyl-idene)amino]-benz-yl}imino-meth-yl)phenol.

Project description:The title compound, C(25)H(26)N(2)O(4), exists in an E conformation with respect to each azomethine link. The two phenol-substituted benzene rings are twisted away from the plane of the diimine benzene ring by dihedral angles of 27.25 (5) and 56.67 (5)°. The mol-ecular structure is stabilized by intra-molecular O-H⋯N hydrogen bonds.

Benzyl N-[(S)-2-hy-droxy-1-({[(E)-2-hy-droxy-4-meth-oxy-benzyl-idene]hydrazin-yl}carbon-yl)eth-yl]carbamate.

Project description:The shape of the title compound, C(19)H(21)N(3)O(6), is curved with the conformation about the imine bond [1.291 (3) Å] being E. While the hy-droxy-substituted benzene ring is almost coplanar with the hydrazinyl residue [N-N-C-C = 177.31 (18)°], an observation correlated with an intra-molecular O-H⋯N hydrogen bond leading to an S(6) ring, the remaining residues exhibit significant twists. The carbonyl residues are directed away from each other as are the amines. This allows for the formation of O-H⋯O and N-H⋯O hydrogen bonds in the crystal, which lead to two-dimensional supra-molecular arrays in the ac plane. Additional stabilization to the layers is afforded by C-H⋯π inter-actions.

N'-(3-Eth-oxy-2-hy-droxy-benzyl-idene)-2-hy-droxy-3-methyl-benzohydrazide.

Project description:The title compound, C(17)H(18)N(2)O(4), crystallizes with two independent mol-ecules in the asymmetric unit. The two benzene rings in each mol-ecule make dihedral angles of 7.6?(3) and 3.9?(3)°. Intra-molecular O-H?N and O-H?O hydrogen bonds are present in each mol-ecule.

The are also a number of C-H?O and ?-? inter-actions present [centroid-centroid distances = 3.874?(4) and 3.904?(3)?Å], that result in the formation of a three-dimensional network.

(E)-4-Hy-droxy-N'-(3-hy-droxy-4-meth-oxy-benzyl-idene)benzohydrazide.

Project description:The mol-ecule of the title benzohydrazide derivative, C(15)H(14)N(2)O(4), exists in a trans conformation with respect to the C=N double bond and is twisted, the dihedral angle between the two benzene rings being 24.17?(6)°.

In the crystal, the mol-ecules are linked by N-H?O and O-H?O hydrogen bonds into sheets parallel to the bc plane. These sheets are further connected into a three-dimensional network by weak C-H?O and C-H?? inter-actions.

(2E)-2-(3-Eth-oxy-2-hy-droxy-benzyl-idene)hydrazinecarboxamide.

Project description:The title compound, C10H13N3O3, adopts an E conformation with respect to the azomethine bond and crystallizes in the amide form.

Pairs of N-H⋯O hydrogen bond link the mol-ecules into centrosymmetric dimers, which are linked by further N-H⋯O hydrogen bonds into chains along the b axis. The chains are linked by C-H⋯π inter-actions.
