Abstract

The asymmetric unit of the title compound, [Eu(NO(3))(C(6)H(5)NO(2))(2)(H(2)O)(4)](NO(3))(2), consists of one-half of the C(2) symmetric coordination cation and one nitrate anion. The eight-coordinated Eu(III) atom is in a distorted dodeca-hedral coordination environment. The coordination cations and nitrate anions are connected via O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network.
