In the title compound, Na+·C10H15O3−·5H2O, the vertices of a distorted octa­hedron centred on the Na+ cation are defined by six O atoms of water mol­ecules. The edge-sharing Na(H2O)6 octa­hedra form a chain extended along the b-axis direction with adjacent Na+ cations related by a twofold screw symmetry operation. The organic anion, which is not in close contact with the Na+ cation, is hydrogen-bonded to an uncoordinated water mol­ecule and to water mol­ecules of the Na(H2O)6 octa­hedra.

Comment top

Sodium nopinate is an intermediate in the synthesis of nopinic acid. Hydroxyalkylamino salts of nopinic acid are new compounds useful in pharmaceutical compositions for alleviating ulcer conditions. In the course of synthesis of nopinic acid the crystal of sodium nopinate pentahydrate (I) was obtained in its crystallographic data are reported here (Fig.1). In the title compound the vertices of a distorted octahedron centred on Na+ cation are defined by six O atoms of water molecules. The edge-sharing Na(H2O)6 octahedra form a chain extended along the b axis with the adjacent Na+ cations related by twofold screw axis symmetry. Similar chains were observed in sodium pyridine-4-carboxylate tetrahydrate (Huang et al., 2005).

Experimental top

Potassium permanganate (0.03 mol) and NaOH (0.015 mol) were dissolved in the mixture of water (21 ml) and t-butylalcohol (9 ml).While stirring vigorously, enantiomerically pure (-)-β-pinene (0.01 mol) was dropped. The reaction mixture was maintained during 1 to 2 h at temperature of 283–293 K. The reaction was completed when the potassium permanganate reacted completely. The mixture was heated to 353 K,then filtered and the precipitate was washed with hot water. The filtrate was concentrated under vacuum to a volume of 10 ml. After standing for one night in refrigerator the product, sodium nopinate, was filtered and washed with ice water. The crude sodium nopinate was recrystallized from water. Analysis calculated for C10H15O3Na: C 58.25, H 7.28, Na11.17%; found: C 58.23, H 7.25, N 11.15%. Crystals of (I) suitable for single-crystal X-ray analysis were selected directly from the sample after recrystallization.

Refinement top

In the absence of signifcant anomalous scattering effects, Friedel pairs were averaged. The chirality of atoms C2, C3 and C5 were assigned from the known hand of the starting material.The H-atoms were included in the riding-model approximation with C—H = 0.96–0.98 Å and O—H = 0.82 Å (O-hydroxy) and 0.85 Å (O-water), and with Uiso(H) = 1.2 or 1.5 Ueq(C) and Uiso(H) = 1.5 (O-hydroxy) or 1.2 (O-water) Ueq(O). Friedel pairs were merged for the refinement process.

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.
