title: (6-Oxido-2-oxo-1,2-dihydropyrimidine-5-carboxylato-κO,O)(4-oxido-2-oxo-1,2-dihydropyrimidin-3-ium-5-carboxyl-ato-κO,O)bis(1,10-phenanthroline-κN,N')erbium(III) dihydrate.
abstract: The erbium(III) atom in the title compound, [Er(C(5)H(2)N(2)O(4))(C(5)H(3)N(2)O(4))(C(12)H(8)N(2))(2)]·2H(2)O, is located on a twofold rotation axis and chelated by two 1,10-phenanthroline heterocycles as well as by a 2,4-dihydroxy-pyrimidine-5-car-box-yl-ate monoanion and a 2,4-dihydroxy-pyrimidine-5-car-box-yl-ate dianion in a square-anti-prismatic coordination geometry.
