To the solution of 2-amino-7-methyl-1,8-naphthyridine (3.18 g, 0.02 mol) in mixed solvent of water (28 mL) and ethanol (2 mL), 37% formadehyde solution (0.86 mL, 0.01 mol) was added dropwise at 0°C and the reaction mixture was stirred at room temperature for 24h. The white precipitate formed was filtered, washed several times with water and then with diethyl ether and dried. Yield: 55% (1.81 g). FTIR (KBr)cm-1: νNH 3389, 3266; νCH 3026. Anal. Calc. For C19H18N6: C, 69.07; H, 5.49; N, 25.44. Found: C, 68.86; H, 5.56; N, 25.37. Single crystals of (I) suitable for an X-ray study were obtained by slow evaporation of an aqueous ethanol solution (30% v/v) under the conditions in the presence of perchloric acid at 293 K over a period of one month.
Hydrogen atoms of NH (naphthyridine and amine) were located in a Fourier map and refined freely. All the other hydrogen atoms were generated geometrically (C—H bond lengths of methyl group fixed at 0.98Å, C—H bond lengths of naphthyridine fixed at 0.95 Å) assigned appropriated isotropic thermal parameters, Uiso(H) = 1.2Ueq(C). Each perchlorate anion is disordered over two different orientations. The Cl–O distances were restrained to 1.43 (4)Å.
1,8-Naphthyridine and its derivatives are used for binding of mismatched guanine or used as versatile ligands which are able to form metal aggregates with monodentates fashion or chelating bidentate fashion(Nakatani et al., 2000; Nakatani et al., 2001; Ferrarini et al., 1997; Gavrilova & Bosnich, 2004; Baker & Norman, 2004; Stadie et al., 2007). We report here a new 1,8-Naphthyridine compound (Fig. 1).
The title compound reveals 1,8-naphthyridine rings are linked by methenediamine with a dihedral angle between two 1,8-naphthyridine rings of 60.6 (1)°. Each 1,8-naphthyridine ring is an almost planar in which the ten atoms forming the 1,8-naphthyridine ring have mean deviation of 0.03Å from the least-squares plane calculated using the ten atoms. To balance hydrogen ion charge of two 1,8-naphthyridine rings, there are two perchlorate groups in crystal cell. From the packing diagram (Fig. 2), it seems that the intramolecular N–H···O and C–H···O and hydrogen bonds are effective in the stabilization of the crystal structure.

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. |

1,8-Naphthyridine and its derivatives are used for binding of mismatched guanine or used as versatile ligands which are able to form metal aggregates with monodentates fashion or chelating bidentate fashion(Nakatani et al., 2000; Nakatani et al., 2001; Ferrarini et al., 1997; Gavrilova & Bosnich, 2004; Baker & Norman, 2004; Stadie et al., 2007). We report here a new 1,8-Naphthyridine compound (Fig. 1).
The title compound reveals 1,8-naphthyridine rings are linked by methenediamine with a dihedral angle between two 1,8-naphthyridine rings of 60.6 (1)°. Each 1,8-naphthyridine ring is an almost planar in which the ten atoms forming the 1,8-naphthyridine ring have mean deviation of 0.03Å from the least-squares plane calculated using the ten atoms. To balance hydrogen ion charge of two 1,8-naphthyridine rings, there are two perchlorate groups in crystal cell. From the packing diagram (Fig. 2), it seems that the intramolecular N–H···O and C–H···O and hydrogen bonds are effective in the stabilization of the crystal structure.
