The crystal structure of lithium l -ascorbate dihydrate

Investigation ofL(+)-Ascorbic acid with Raman spectroscopy in visible and UV light

“…The crystal structures of several salts of AH 2 have been obtained, including the sodium salt NaAH (10), as well as calcium (27)(28)(29), strontium (30), lithium (31), thallium (32), and other ascorbates (33). The crystal structures were often found to contain various amounts of hydrate water in addition to one or more ascorbate ions that look much like the AH 2 depicted in Figure 1, although without H3.…”

“…The Na + and K + cations will energetically prefer formation of the bicoordination complex through the O 2 and O 3 sites of AAO anion both in the gas phase and in water solution. It is important to note that the experimental results do imply a preferred interaction site for ascorbate–metal complexes; however, the structure of metal–ascorbate is complex, and metals are involved in coordination with more than one anion and with water molecules 6–12.…”

“…Few studies have evaluated some of the structural properties of ascorbic acid and its interactions with various metals 6–13. Hvoslef 6 employed the X‐ray diffraction technique to determine the changes in ascorbic acid consequent to ionization and the interaction of sodium with ascorbate.…”

“…Davies 11 compiled a comprehensive review of the reactions of L ‐ascorbic acid with transition metal complexes. Koziol and Stepniak 12 investigated the crystal structure of lithium L ‐ascorbate, using the X‐ray diffraction method and found that lithium does not prefer to bind the O 3 site of the molecule. There are limited theoretical data concerning the interaction of ascorbic acid with metal cations.…”

Studies on lithium l-ascorbate dihydrate: An interesting chiral nonlinear optical crystal

“…L-ascorbic acid is a sugar acid and is classified as a monosaccharide [2e4]. The crystal structure of LLA was solved by Koziol et al [5]. LLA crystallizes in triclinic space group P1 with lattice parameters a ¼ 5.964 A, b ¼ 5.299 A, c ¼ 7.760 A, a ¼ 100.82 , b ¼ 109.78 , g ¼ 92.02 and Z ¼ 1.…”
