Crystal structure of 2-benzoylamino-it N'-(4-hydroxybenzylidene)-3-(thiophen-2-yl)prop-2-enohydrazide
MetadataShow full item record
In the title compound, C21H17N3O3S, the non-H atoms, apart from those in the benzoyl group, are almost coplanar (r.m.s. deviation = 0.049 Å) and the benzoyl group is almost orthogonal to the plane of the rest of the molecule [dihedral angle = 80.34(6)º]. In the crystal, a combination of N---H···O and asymmetric bifurcated O---H···(N,O) hydrogen bonds link the molecules into a three-dimensional network. Weak C---H···O interactions are also observed.
