(E)-N'-[(2-Hydroxy-1-naphthyl)methyl-ene]benzohydrazide monohydrate.

ABSTRACT: In the title compound, C(18)H(14)N(2)O(2)·H(2)O, the dihedral angle between the benzene ring and the naphthalene system is 5.18 (10)°. Intra-molecular N-H⋯O hydrogen bonds influence the molecular conformation. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds are observed as well as π-π inter-actions between the phenyl ring and the substituted ring of the naphthalene [centroid-centroid distance = 3.676 (11) Å].

(E)-3-(1-Naphthyl-amino)-methyl-ene-(+)-camphor.

Project description:In the crystal structure of the title ketoamine {systematic name: (E)-1,7,7-trimethyl-3-[(1-naphthyl-amino)-methyl-idene]bicyclo-[2.2.1]heptan-2-one}, C(21)H(23)NO, there are two independent mol-ecules in the asymmetric unit. Both mol-ecules have an E configuration about the alkene function. The main conformational difference between the mol-ecules is in the orientation of the plane of the naphthyl rings with respect to the camphor fragment. The torsion angle about the enamine C-N bond is 21.3 (7)° for mol-ecule A, but -24.4 (8)° for mol-ecule B. Inter-molecular N-H⋯O hydrogen bonds between the amino and ketone groups of adjacent independent mol-ecules sustain the crystal, and the resulting extended chains, containing an alternating sequence of the two independent mol-ecules, run parallel to the [001] direction and can be described by a graph-set motif of C(2) (2)(12).
