(E)-4-Methoxy-N′-[(6-methyl-4-oxo-4H-chromen-3-yl)methylidene]benzohydrazide monohydrate
In the title hydrate, C19H16N2O4·H2O, the 4H-chromen-4-one segment is slightly twisted, with a dihedral angle between the two six-membered rings of 3.30 (5)°. The dihedral angles between the plane of the pyran-one ring and the hydrazide plane and between the planes of the pyran-one ring and the benzene ring of the p-meth-oxy-benzene unit are 26.69 (4) and 2.23 (3)°, respectively. The mol-ecule ...

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...
متن کاملEthyl (E)-3-(6-methyl-4-oxo-4H-chromen-3-yl)prop-2-enoate
In the title compound, C(15)H(14)O(4), the chromone ring system is close to being planar [maximum deviation = 0.015 (2) Å]. The double bond of the ethyl prop-2-enoate chain adopts an E conformation and an intra-molecular C-H⋯O hydrogen bond generates an S6 ring. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R(2) (2)(14) loops. Weak π-π inter-actions [centroid...

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 benz...

In the title chromone-tethered benzohydrazide derivative, C20H18N2O6, the atoms of the E-3-(hydrazonometh-yl)-4H-chromen-4-one segment are essentially coplanar, the largest deviation being 0.065 (6) Å. The dihedral angle between this segment and the benzene ring of the tri-meth-oxy-benzene unit is 40.18 (10) Å. In the crystal, the mol-ecule is linked to its inverse-symmetry equivalent by pairs ...
