R. Cuesta et al., [6-amino-3-methyl-5-nitroso-pyrimidine-2,4(1H,3H)-dionato]-sodium dihydrate at 150 K: coordination-polymer ladders linked by hydrogen bonds, ACT CRYST C, 57, 2001, pp. 918-921
In the title compound, [Na(C5H5N4O3)]. 2H(2)O, each Na cation is linked to
three C5H4N4O3- anions and two water molecules, forming approximately octah
edral NaNO5 units; the cations and the anions form molecular ladders, and e
ach ladder is linked to four neighbouring ladders by O-H . . .O and O-H . .
.N hydrogen bonds.
