title: Poly[[tetra-aquadi-μ(3)-oxalato-μ(2)-oxalato-diprasedymium(III)] dihydrate].
abstract: 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.
