Poly[μ₂-L-alanine-μ₃-nitrato-sodium(I)]

Abstract

Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.003 Å; R factor = 0.037; wR factor = 0.092; data-to-parameter ratio = 10.2.The title compound, [Na(NO 3 )(C 3 H 7 NO 2 )] n , was obtained unintentionally as the product of an attempted reaction of sodium molybdate in aqueous solution and the amino acid l-alanine (ala), in order to obtain a -type octamolybdate, Na 4 [Mo 8 O 26 (ala) 2 ].18H 2 O, coordinated by l-alanine. The coordination geometry around the Na atom can be considered as trigonal-bipyramidal, with three bidentate nitrate anions coordinating through their O atoms and two l-alanine molecules each coordinating through one carboxylate O atom.

Study of the phase equilibria in the L-alanine - sodium nitrate system by optical microscopy and X-ray powder diffraction

“…Among the organic materials, amino acids are of particular interest since they have relevant implications for biological systems [1]. In addition, they can form semi-organic (hybrid) materials in combination with inorganic salts [2,3]. A key to optimizing their physical and chemical properties is to control their final crystalline form.…”
