Poly[diaquabis­(μ(4)-fumarato-κ(4) O (1):O (1′):O (4):O (4′))(μ(4)-fumarato-κ(6) O (1):O (1),O (1′):O (4):O (4),O (4′))(μ(2)-fumaric acid-κ(2) O (1):O (4))dipraseodymium(III)]

The title complex, [Pr(2)(C(4)H(2)O(4))(3)(C(4)H(4)O(4))(H(2)O)(2)](n), was synthesized by reaction of praseodymium(III) nitrate hexa­hydrate with fumaric acid in a water–ethanol (4:1) solution. The asymmetric unit comprises a Pr(3+) cation, one and a half fumarate dianions (L (2−)), one half-mol­ec...
