Poly[[diaquamanganese(II)]-mu(3)-4-oxido-2-oxo-1,2-dihydropyrimidine-5-carboxylato-kappa4O4,O5:O2:O2].
In the title compound, [Mn(C5H2N2O4)(H2O)2]n, the Mn(II) ion has a distorted octahedral geometry and the 4-oxido-2-oxo-1,2-dihydropyrimidine-5-carboxylate (Hiso(2-)) anion acts as a mu3:eta(4)-bridging ligand. Two oxo O atoms from different Hiso(2-) ligands bridge two Mn(II) ions, forming centrosymmetric dinuclear building blocks. Each dinuclear building block interacts with another four by the coordination of the oxide groups and carboxylate O atoms, producing a two-dimensional framework in the ab plane. Hydrogen bonds further extend the two-dimensional sheets into a three-dimensional supramolecular framework.
