Tris(3-amino-pyrazine-2-carboxyl-ato-?N,O)diaqua-erbium(III) tetra-hydrate.


ABSTRACT: The water-coordinated Er(III) atom in the title compound, [Er(C(5)H(4)N(3)O(2))(3)(H(2)O)(2)]·4H(2)O, is N,O-chelated by three 3-amino-pyrazine-2-carboxyl-ate ions and has a square-anti-prismatic geometry. The mononuclear mol-ecule inter-acts with the solvent water mol-ecules to generate a three-dimensional hydrogen-bonded network.
