Abstract top

In the title compound, C18H14N2O3, the dihedral angle between the planes of the naphthalene and phenyl ring systems is 2.64 (2)°. Molecules are engaged in [pi]-[pi] stacking (mean interplanar distance = 3.339 between naphthalene rings and 3.357 Å between benzene rings )and hydrogen-bonding interactions.

Comment top

Metallacrowns are a new class of metallamacrocycles, which have gained increasing attention over the past decade because of their potentially unique properties (Alexiou et al., 2002; Gaynor et al., 2002; Lah & Pecoraro, 1989; Lehaire et al., 2002; Liu et al., 2001; Saalfrank et al., 2001). These metallacrowns exhibit selective recognition of cations and anions (Saalfrank et al., 2001; Lehaire et al., 2002), can display intramolecular magnetic exchangeinteractions (Liu et al., 2001), and can be used as building blocks for two-dimensional or three-dimensional network structures (Gaynor et al., 2002; Lah & Pecoraro, 1989; Lehaire et al., 2002). The ability to control the generation of metallacrowns with different nuclear numbers, desired structures, and properties is still a substantial challenge. We now report structure of a designed pentadentate ligand, 3-hydroxy-N-phenyl-2-naphthalenecarbohydrazide (I).

The molecular structure of (I), C18H14N2O3, is illustrated in Fig.1. The bond length and bond angles in (I)are within normal ranges. The dihedral angle between the planes of naphthalene and benzene rings is 2.640 (2)°. Atom O2 is only approximately co-planar with the naphthalene plane and deviates from the benzene plane by 0.788 (2)Å. The maximum atomic deviation (O3) from the naphthalene plane is 1.403 (2)Å.

The mean interplanar distance of 3.339Å between naphthalene rings and 3.357Å between benzene rings suggests that the ligands are engaged in π-π stacking interactions (Fig. 2). The crystal structure of (I) is stabilized by O—H···O and N—H···O hydrogen bonding (Table 1).

Experimental top

Acetic anhydride (6.8 g, 66.8 mmol) and 3-hydroxy-2-naphthalenecarbohydrazide (11.3 g, 56.0 mmol) were added to 120 ml of chloroform with an external ice-water bath. The reaction mixture was slowly warmed to room temperature and stirred for 8 h. After leaving overnight in a refrigerator, the resulting white precipitate was filtered and rinsed with chloroform and diethyl ether. Yield: 95.3%. Melting point: 492 - 496 K. Calcd. for C18H14N2O3: C, 70.58; H, 4.61; N, 9.15%; Found: C, 70.24; H, 4.75; N, 9.02%.

Refinement top

All H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms (C—H = 0.93%A; N—H = 0.86Å; O—H = 0.82 Å) and Uiso(H) values weren taken to be equal to 1.2 Ueq(C, N) and 1.5Ueq(O). The hydroxy proton was located from from difference Fourier maps. In the absence of significant anomalous scattering effects, Friedel pairs wer merged.

Special details top

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.
