(Received 15 November 2007; accepted 23 November 2007; online 6 December 2007)

In the title compound, [Cd(NO3)2(C10H11N3)2], two naph­thyridine ring systems are coordinated to the Cd ion through the two N atoms in a bidentate chelating mode, whereas the remaining coordination sites are occupied by two O atoms from two different nitrate groups to complete the octahedral geometry. Inter­moleular N—H⋯O hydrogen bonds link the mol­ecules to form a one-dimensionnal sheet parallel to the ac plane. Weak slipped π–π stacking involving the naphthyridine ring systems stabilizes the structure.

Comment top

Molecular structures and chemical properties of transition metal complexes of 1,8-naphthyridine (napy) and its derivatives have received much attention(Kukrek et al., 2006; Che et al., 2001), because the ligands can link to metals with several coordination modes such as monodentate, chelating bidentate, and dinuclear bridging binding fashion (Gavrilova & Bosnich, 2004). 5,7-dimethyl-1,8-naphthyridin-2-amine (L) is a potentially tridentate ligand and is capable of linking two to four metal atoms together to form metal aggregates (Oskui et al., 1999; Mintert & Sheldrick, 1995a; Oskui & Sheldrick, 1999; Mintert & Sheldrick, 1995b). The coordination chemistry of 5,7-dimethyl-1,8-naphthyridine-2-amine has not been well studied before although a series of transiton metal complex (M(L)2Cl2) were once described in a US patent (Bayer, 1979). As an extension of our study on naphthyridine coordination chemistry(Jin et al., 2007), herein the title complex [Cd(L)2(NO3)2] is reported.

In the title compound, two naphthyridine are coordinated to the Cd ion through two nitrogen atoms in bidentate chelating mode whereas the remaining coordination sites are occupied by two oxygen atoms from two different nitrates (Fig. 1). The two nitrate ligands display a dissymetric chelating mode with Cd—O distances of 2.357 (4) and 2.718 (4). The remaining distances are within the usual range. The two naphthyridine rings were almost perpendicular to each other making dihedral angle of 80.22 (7)°. The two chelating Cd—O—N—O group make dihedral angle of 81.21 (12)°.

Intermoleular N—H···O hydrogen bonds link the molecules to form a one dimensionnal sheet parallel to the a axis (Table 1, Fig. 2). Weak slippest π-π stackings involving the naphthyridine rings stabilize the structure (Table 2).

Experimental top

All reagents and solvents were used as obtained without further purification. The CHN elemental analyses were performed on a Perkin-Elmer model 2400 elemental analyzer. A solution of cadmium nitrate tetrahydrate (31.4 mg, 0.1 mmol) in methanol (3 ml) was added to L (52.2 mg, 0.3 mmol) in methanol (10 ml) to give a colorless solution. The methanol solution was filtered. The solution was left standing at room temperature for several days, colorless block crystals were isolated. Yield: 41 mg, 70.3%. Anal.

All H atoms attached to C atoms and N atom were fixed geometrically and treated as riding with C—H = 0.93 Å (aromatic) or 0.96 Å (methyl) and N—H = 0.86 Å with Uiso(H) = 1.2Ueq(Caromatic or N) or Uiso(H) = 1.5Ueq(Cmethyl).

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.
