腺苷-Y-磷酸一水合物在正交晶系空间群P212121中结晶，
a=22“997（2），B=9.406（1），c=6.599（1）A，Z=4.结构用直接法求解，
对于在自动衍射仪上测量的1320个有效反射，将其细化到0.0639的最终Rw。
该分子的构象与以前报道的单斜晶系分子的构象有很大不同。
[Kraut &詹森，晶体学报（1963），16，79-88]。例如，糖的构象，
在这里是C（2 π ′-内，糖苷扭转角改变了几乎50 °。
Adenosine-Y-phosphate monohydrate was crystallized in the orthorhombic space group P212121, with
a=22"997 (2), b=9.406 (1), c=6.599 (1)A,, Z=4. The structure was solved by direct methods and
refined to a final Rw of 0.0639 for 1320 significant reflexions measured on an automatic diffractometer.
The conformation of the molecule differs significantly from that previously reported for the monoclinic
monohydrate [Kraut & Jensen, Acta Cryst. (1963), 16, 79-88]. The sugar conformation, for example,
is here C(2)'-endo, and the glycosidic torsion angle has altered by almost 50 °.
