Abstract
The title compound {(C3H5N2)2[Pr2(C7H3NO4)4(H2O)4]}n, has a chain structure featuring a dimeric unit consisting of two PrIII atoms within a dodecahedral environment. Each of the metal cations is coordinated by two N atoms and two O atoms from two pyridine-2,5-dicarboxylate ligands, two O atoms from another two pyridine-2,5-dicarboxylate ligands and two water O atoms. The PrIII ions are bridged by two ligands along the c axis, forming the dimeric unit, and these are connected by four ligands along the b axis, forming a chain. N—H⋯O and O—H⋯O hydrogen bonds are found in the structure.
