L-Serine and DL-serine have been treated with oxalic acid under different experimental conditions, e. g. crystallization from solution and slurry, kneading and dry mixing, yielding the molecular salts [L-serH](2)[ox]center dot 2H(2)O forms I and II, [L-serH][Hox] and [DL-serH](2)[ox]center dot 2H(2)O, all fully characterized by powder or single crystal X-ray diffractions; the relationship between the different crystal forms, relative thermal stability, dependence on relative humidity and possible interconversions have all been explored.

Abstract
L-Serine and DL-serine have been treated with oxalic acid under different experimental conditions, e. g. crystallization from solution and slurry, kneading and dry mixing, yielding the molecular salts [L-serH](2)[ox]center dot 2H(2)O forms I and II, [L-serH][Hox] and [DL-serH](2)[ox]center dot 2H(2)O, all fully characterized by powder or single crystal X-ray diffractions; the relationship between the different crystal forms, relative thermal stability, dependence on relative humidity and possible interconversions have all been explored.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
