(E)-3,4,5-Trimeth-oxy-N'-[(6-meth-oxy-4-oxo-4H-chromen-3-yl)methyl-idene]benzohydrazide monohydrate.

ABSTRACT: In the title chromone-tethered benzohydrazide derivative, C21H20N2O7·H2O, the atoms of the 4H-chromen-4-one segment are essentially coplanar (r.m.s. deviation = 0.0073?Å) with the largest deviation from the mean plane [0.012?(3)?Å] being found for the benzene C atom. The dihedral angles between the chromone segment and the hydrazide plane and between the chromone segment and the benzene ring of the tri-meth-oxy-benzene unit are 24.67?(9) and 41.28?(8)?Å, respectively. The mol-ecule is connected to the solvent water mol-ecule by O-H?O hydrogen bonds and weak C-H?O inter-actions. Additional N-H?O inter-actions are observed and together they link the mol-ecules into chains forming a two-dimensional network along (011).

In the title chromone-tethered benzohydrazide derivative, C21H20N2O7·H2O, the atoms of the 4H-chromen-4-one segment are essentially coplanar (r.m.s. deviation = 0.0073 Å) with the largest deviation from the mean plane [0.012 (3) Å] being found for the benzene C atom. The dihedral angles between the chromone segment and the hydrazide plane and between the chromone segment and the benzene ring of the tri-meth-oxy-benzene unit are 24.67 (9) and 41.28 (8) Å, respectively.

The -CH=N-NH- segment is stacked on the benzene ring of the chromone unit of a translation-related equivalent mol-ecule [centroid-centroid distance = 3.413 (6) Å].

Project description:In the asymmetric unit of the title compound, C(18)H(20)N(2)O(5), there are two crystallographic independent mol-ecules. Both mol-ecules are twisted; the dihedral angle between the two benzene rings is 7.2?(5)° in one mol-ecule, whereas it is 85.9?(4)° in the other. Of the three meth-oxy groups in the 3,4,5-trimeth-oxy-phenyl unit, two meth-oxy groups at meta positions are approximately coplanar with the benzene plane [C-O-C-C torsion angles of -2.3?(13)-4.8?(11)°], but the other meth-oxy, at the para position, is out of the plane [C-O-C-C of 72.8?(9)° in one mol-ecule and -77.5?(9)° in the other]. In the crystal, mol-ecules are linked by N-H?O hydrogen bonds and weak C-H?O inter-actions into tapes along the b axis. C-H?? inter-actions are also present.

Project description:The title benzohydrazide derivative, C(17)H(18)N(2)O(5), exists in a trans conformation with respect to the C=N double bond. The dihedral angle between the benzene rings is 19.41?(5)°. The two meth-oxy groups at the meta positions of the trimeth-oxy-benzene group are almost coplanar with the ring [C-O-C-C = 1.62?(16) and 178.33?(10)°], whereas the third meth-oxy group, at the para position, is (+)-synclinal with the ring. In the crystal, mol-ecules are linked by N-H?O and bifurcated O-H?(N,O) hydrogen bonds, as well as weak C-H?O inter-actions, into sheets lying parallel to the ac plane. A C-H?? inter-action also occurs.

(E)-4-Methyl-N'-[(4-oxo-4H-chromen-3-yl)methyl-idene]benzohydrazide.

Project description:In the title chromone-tethered benzohydrazide derivative, C18H14N2O3, the 4H-chromen-4-one and the -CH=N-NH-CO- units are each essentially planar, with the largest deviations from thei planes being 0.052?(2) and 0.003?(2)?Å, respectively. The dihedral angles between the 4H-chromen-4-one and the -CH=N-NH-CO- units, the 4H-chromen-4-one unit and the benzene ring of the 4-tolyl group, and the benzene ring of the 4-tolyl group and the -CH=N-NH-CO- unit are 8.09?(7), 9.94?(5) and 17.97?(8)°, respectively. In the crystal, the mol-ecules form two types of centrosymmetric dimers: one by N-H?O hydrogen bonds and the other by ?-? stacking inter-actions between the 4H-chromen-4-one unit and the 4-tolyl group [centroid-centroid distance = 3.641?(5)?Å]. These dimers form one-dimensional assemblies extending along the a-axis direction. Additional ?-? stacking inter-actions between two 4H-chromen-4-one units [centroid-centroid distance = 3.591?(5)?Å] and two 4-tolyl groups [centroid-centroid distance = 3.792?(5)?Å] organize the mol-ecules into a three-dimensional network.

Project description:In the title compound, C(15)H(15)N(3)O(3)·H(2)O, the hydazide Schiff base mol-ecule shows an E conformation around the C=N bond.

The water mol-ecule mediates linking of neighbouring mol-ecules through O-H?(O,O) hydrogen bonds into infinite chains along the a axis, which are further connected together through N-H?O hydrogen bonds, forming a two-dimensional network parallel to (001). C-H?O inter-actions aso occur.
