Abstract	:	The asymmetric unit of the polymeric title compound, {[Pr 2(C5H4N3O2) 5(CHO2)(H2O)5]·6H 2O}n, has two independent PrIII atoms; one is coordinated by two water molecules and the other by three water molecules. The first is N,O-chelated by three 3-aminopyrazine-2-carboxylate ions, whereas the second is chelated by two carboxylate ions; both exist in a monocapped squareantiprismatic geometry. The polymeric chains that run along the a axis interact with the lattice water molecules, generating a threedimensional hydrogenbonded network. The formate ion is disordered over two positions with respect to the noncoordinated atoms in a 1:1 ratio.
