Source of materials
To a solution of 4-phenylsemicarbazide (0.151 g, 1 mmol) in heated absolute ethanol (20 mL) was added slowly a heated ethanol solution (20 mL) of 4-methoxy-2-butanone (0.102 g, 1 mmol) while stirring for 20 min. The white precipitate was filtered, washed with cold ethanol and dried in vacuo. Single crystals were grown at room temperature from slow evaporation of a mixture of ethanol and acetonitrile (1:1 v/v). IR (cm−1) 3338 (N—H), 1665 (C=O), 1597 (C=N), 1239 (C—N), 1025 (C=S). MS: m/z 311.25 [M]+.
Experimental details
The C-bound H atoms were geometrically placed (C—H = 0.95−0.99 Å) and refined as riding with Uiso(H) = 1.2–1.5 Ueq(C). The N-bound H-atoms were located in a difference Fourier map but were refined with a distance restraint of N—H = 0.88 ± 0.01 Å, and with Uiso(H) set to 1.2 Ueq(N).
Comment
It is well known that the condensation of semicarbazides with aldehydes/ketones gives rise to a class of potential Schiff base ligands. These molecules attract interest in terms of potential biological activity, most notably in the context of their anti-convulsant properties with the 4-(4-fluorophenoxy)benzaldehyde semicarbazone being the subject of considerable investigations in this regard [5]. In connection with on-going studies of the biological activity of transition metal thiosemicarbazone complexes [6], recently the synthesis and characterization of a new Schiff base ligand, derived from the reaction of aryl semicarbazide and vanillylacetone, was described [7]. In continuation of these studies, the title Schiff base molecule was characterized.
Two independent molecules comprise the asymmetric unit of the title compound. As seen from the Figure (70% displacement ellipsoids), the molecules present many similarities but, with the obvious difference related to the relative disposition of the methoxyphenyl residues. The molecule comprises a di-substituted urea residue. At one end, there is a phenyl ring while at the other, an imine (Z-configuration) group connects the urea residue to the 4-methoxyphenyl ring via an ethane link. The four atoms of the urea core are strictly planar with a r.m.s. deviation of 0.0004 Å for the fitted atoms [0.0014 Å for the O3-molecule]. The amine-N—H and imine-N atoms are syn, a disposition that enables the formation of intramolecular amine-N–H⋯N(imine) hydrogen bonds [N1—H1n⋯N3: 2.111(16) Å and 113.8(14)°; N4—H4n⋯N6: 2.125(16) Å and 113.7(13)°]. The dihedral angle between the CN2O plane and the adjacent phenyl ring is 3.85(13)° [7.54(12)°], consistent with a co-planar relationship. The dihedral angles between the outer phenyl rings are 37.56(8) and 66.56(5)° for the O1- and O3-molecules, respectively.
The most prominent feature of the molecular packing is the formation of an eight-membered {⋯HNCO}2 amide synthon formed between the two independent molecules comprising the asymmetric unit [N2—H2n⋯O3: 2.001(14) Å and 171.0(18)°; N5—H5n⋯O1: 1.956(14) Å and 172.8(17)°].
There is a sole literature precedent for molecules of this type as discussed recently [7]. The structure of this molecule, derived from the reaction of semicarbazide and vanillylacetone, presents very similar features to that described above.
