(μ-6-Oxido-4-oxo-1,2-dihydro­pyrimidine-5-carboxyl­ato-κ(4) O (5),O (6):O (2),N (3))bis­[aquabis­(4-oxido-2-oxo-1,2-dihydro­pyrimidin-3-ium-5-carboxyl­ato-κ(2) O (4),O (5))­(1,10-phenanthroline-κ(2) N,N′)neodymium(III)] hexa­hydrate

The water-coordinated neodymium(III) atom in the centrosymmetric title compound, [Nd(2)(C(5)H(2)N(2)O(4))(C(5)H(3)N(2)O(4))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)]·6H(2)O is chelated by a 1,10-phenanthroline heterocycle and two 2,4-dihydroxy­pyrimidine-5-carboxyl­ate dianions. Two tris-chelated water-coordinated units are bridged by a 2,4-dihydroxy­pyrimidine-5-carboxyl­ate dianion, which is disordered about a center of inversion. The metal center has a monocapped square-anti­prismatic coordination.
