Triaqua­[2-(6-oxido-4-oxo-3,4-dihydro­pyimidin-2-ylsulfan­yl)acetato]nickel(II) 2.5-hydrate.

In the crystal structure of the title compound, [Ni(C6H4N2O4S)(H2O)3]·2.5H2O, the NiII atom is six-coordinated by one 2-(6-oxido-4-oxo-3,4-dihydro­pyimidin-2-ylsulfan­yl)­acetate ligand and three water mol­ecules. Hydrogen-bonding inter­actions between the coordinated and uncoordinated water mol­ecules and between the water mol­ecules and the organic ligand result in a three-dimensional network structure.
