title: catena-Poly[[(pyrimidine-2-carb-oxy-lic acid)iron(II)]-μ-oxalato].
abstract: In the title complex, [Fe(C(2)O(4))(C(5)H(4)N(2)O(4))](n), the Fe(II) ion is coordinated by two oxalate anions and a pyrimidine-2-carb-oxy-lic acid ligand in a slightly distorted octa-hedral geometry. Each oxalate anion chelates to two Fe(II) ions, forming chains along the a axis. The chains are further connected by O-H⋯O and C-H⋯O hydrogen bonds, stabilizing the structure. An intra-molecular O-H⋯N inter-action results in a five-membered ring.
