چکیده
In the title complex, [Pr(2)(C(2)O(4))(3)(H(2)O)(4)](n), the two independent Pr(III) ions are both nine-coordinated in a distorted monocapped square-anti-prismatic geometry by seven O atoms from four oxalate ligands and two water mol-ecules. The Pr(III) ions are bridged by the oxalate ligands, forming a layer parallel to (001). O-H⋯O hydrogen bonds connect the layers.

In the title compound, {[Pr(2)(C(2)O(4))(3)(H(2)O)(4)]·2H(2)O}(n), the three-dimensional network structure has the Pr(III) ion coordinated by nine O atoms in a distorted tricapped trigonal-prismatic geometry. The coordinated and uncoordinated water mol-ecules inter-act with the carboxyl-ate O atoms to consolidate the network via O-H⋯O hydrogen bonds.
