Tetra-aqua-(1,10-phenanthroline-5,6-dione-κN,N')cobalt(II) dinitrate.

ABSTRACT: The asymmetric unit of the title compound, [Co(C(12)H(6)N(2)O(2))(H(2)O)(4)](NO(3))(2), consists of a Co(II) complex cation with twofold rotational symmetry and two nitrate anions. The Co(II) atom has a distorted octa-hedral geometry with the basal plane occupied by two 1,10-phenanthroline-5,6-dione N atoms and two aqua O atoms, with the other two aqua ligands in axial positions. The aqua ligands are involved in extensive hydrogen bonding to nitrate and 1,10-phenanthroline-5,6-dione O atoms.
