The 18H24N2O)2](NO3)2, consists of one half of the centrosymmetric nickel(II) complex cation and a nitrate anion. The NiII atom, lying on an inversion center, is four-coordinated by the phenolate O atoms and imine N atoms of two Schiff base ligands, forming a square-planar geometry. The O- and N-donor atoms are mutually trans. In the the nitrate anions are linked to the complex cations by intermolecular N—H⋯O hydrogen bonds.

2-Hydroxy-1-naphthaldehyde (0.1 mmol, 17.2 mg) and N,N-diethylpropane-1,3-diamine (0.1 mmol, 13.0 mg) were mixed and stirred in methanol (10 ml) for 30 min. Then a methanol solution (5 ml) of nickel nitrate (0.1 mmol, 29.1 mg) was added to the mixture. The final mixture was stirred for another 30 min to give a red solution. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of the solution at room temperature.
H2 atom was located from a difference Fourier map and refined isotropically, with the N–H distance restrained to 0.90 (1) Å, and with Uiso(H) fixed at 0.08 Å2. The remaining H atoms were positioned geometrically (C—H = 0.93–0.97 Å) and refined using a riding model, with with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(Cmetyl). Rotating group models were used for the methyl groups.
Schiff bases are known to be versatile ligands in coordination chemistry (Hamaker et al., 2010; Wang et al., 2010; Mirkhani et al., 2010; Liu & Yang, 2009). A large number of complexes with
have been reported because of their interesting structures and potential applications (Keypour et al., 2009; Adhikary et al., 2009; Peng et al., 2009). We report here the of the title new nickel complex with the Schiff base ligand 1-[(3-diethylaminopropylimino)methyl]naphthalen-2-ol.The compound consists of a centrosymmetric mononuclear nickel complex cation and two nitrate anions (Fig. 1). The Ni atom, lying on the inversion center, is four-coordinated by two phenolate O atoms and two imine N atoms from two Schiff base ligands, forming a square planar geometry. The bond lengths (Table 1) around the Ni atom are comparable to those observed in similar nickel complexes (Bhatia et al., 1983; Kamenar et al., 1990; Connor et al., 2003; Lacroix et al., 2004).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Schiff bases are known to be versatile ligands in coordination chemistry (Hamaker et al., 2010; Wang et al., 2010; Mirkhani et al., 2010; Liu & Yang, 2009). A large number of complexes with Schiff bases have been reported because of their interesting structures and potential applications (Keypour et al., 2009; Adhikary et al., 2009; Peng et al., 2009). We report here the crystal structure of the title new nickel complex with the Schiff base ligand 1-[(3-diethylaminopropylimino)methyl]naphthalen-2-ol.
The compound consists of a centrosymmetric mononuclear nickel complex cation and two nitrate anions (Fig. 1). The Ni atom, lying on the inversion center, is four-coordinated by two phenolate O atoms and two imine N atoms from two Schiff base ligands, forming a square planar geometry. The bond lengths (Table 1) around the Ni atom are comparable to those observed in similar nickel complexes (Bhatia et al., 1983; Kamenar et al., 1990; Connor et al., 2003; Lacroix et al., 2004).
In the crystal structure, the nitrate anions are linked to the complex cations by intermolecular N2—H2···O2 and N2—H2···O3 hydrogen bonds.
