Bottom Line: In the title complex, [Pr(C(6)H(4)NO(3))(C(2)O(4))(H(2)O)(2)](n), each Pr(III) ion is coordinated by eight O atoms from two 2-oxynicotinate ligands, two oxalate ligands and two water mol-ecules, displaying a distorted bicapped square-anti-prismatic geometry.The carboxyl-ate groups link adjacent praseodymium metal centres, forming layers parallel to the bc plane.The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.
