The title compound, C13H17NO2, has an intramolecular N—H⋯O hydrogen bond, forming a planar six-membered ring with a mean deviation of 0.015 (5) Å from the plane. This plane makes a dihedral angle of 7.19 (8)° with the adjacent phenyl ring. Through an intermolecular O—H⋯O hydrogen bond, the molecules with their 21 screw and b-translation equivalents form a helical chain running parallel to the b axis.

The title Schiff base ligand was synthesized by the condensation of 3-amino-1-propanol and benzoylacetone. To 0.1 molar solution of 3-amino-1-propanol (dissolved in 5 ml of ethanol) was slowly added to a 0.1 molar solution (in ethanol) of benzoylacetone. The reaction mixture was refluxed for 30 min. The solution was cooled overnight and the precipitate was washed with ethanol. The compound was crystallized in ethanol by slow evaporation (m.p. = 394 K). Anal.

All the hydrogen atoms could be located in a difference Fourier map. However, the H atoms except that of NH, were fixed at geometrically meaningful positions and refined using riding model. The riding tertiary CH3 hydrogen atoms were assigned 1.5 times the equivalent displacement parameters of parent atoms, while 1.2 times was assigned for CH2 and aromatic H atoms. The aromatic C—H distances were fixed at 0.93 Å while the secondary CH2 and tertiary CH3 were assigned 0.97 Å and 0.96 Å respectively. The isotropic displacement parameter of hydroxyl hydrogen was refined. In the absence of significant
effects, Friedel pairs have been merged.Data collection: APEX2 (Bruker, 2004); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The Schiff base 1-phenyl-3-[(3-hydroxypropyl)amino]-1-butanone could be a good chelating ligand and may find use in the field of coordination chemistry of transition metal complexes. The compound could act as a bidentate ligand through the N and O atoms. The replacement of oxygen by nitrogen in the ligand can increase the covalency of the complexes (Morozova et al., 2007).
Figure 1 gives ORTEP representation of the molecule with atoms represented as 50% anisotropic ellipsoids. Figure 2 gives packing of the molecules showing hydrogen bonded interactions. The molecules and their 21 screw translation equivalents are bound through O2—H2A···O1 hydrogen bonds (Table 1). These H-bonded pairs are further linked with their b-translation equivalents to form an one-dimensional hydrogen bonded network parallel to b axis. There is an intramolecular N1—H1···O1 hydrogen bond between the imino hydrogen and the keto oxygen (Table 1). The packing is further stabilized through van der Waals interactions. The crystal is found to cleave easily through the (001) plane. The closely related compound, C12H15O2N, (3-[(2-hydroxyethyl)amino]-1-phenylbut-2-en-1-one) crystallizes in monoclinic system with centrosymmetric space group P21/n, forming hydrogen bonded dimers in the structure (Shi, 2005), while the title compound crystallizes in polar space group P212121 and with extended hydrogen bonding in the structure.
