Beschreibung
Zusammenfassung:	The invention relates to an antiviral medicine, and specifically relates to crystals of an acyclic nucleotide analogue represented by a formula I. the crystals can be crystals of free alkali of the acyclic nucleotide analogue represented by the formula I, and can be crystals of a composition of the acyclic nucleotide analogue represented by the formula I and salts formed by various inorganic acids or organic acids. The characteristics of the crystals can be determined by X-ray powder diffraction analysis spectra and melting points.
