Tetra­aqua­(pyrimidine-4,6-dicarboxyl­ato-κ²N¹,O⁶)magnesium monohydrate

In the title compound, [Mg(C₆H₂N₂O₄)(H₂O)₄]·H₂O, the Mg^II ion is coordinated by a fully deprotonated pyrimidine-4,6-dicarboxyl­ate mol­ecule, via a ring N and a carboxyl­ate O atom, and by four water O atoms at the apices of a slightly distorted octa­hedron. In the crystal, mol­ecules are linked by O—H...O and O—H...N hydrogen bonds, forming a three-dimensional network.
