Tetraaqua(1,10-phenanthroline-5,6-dione-²N,N')cobalt(II) dinitrate

W.-J. Shi

Abstract: The asymmetric unit of the title compound, [Co(C₁₂H₆N₂O₂)(H₂O)₄](NO₃)₂, consists of a Co^II complex cation with twofold rotational symmetry and two nitrate anions. The Co^II atom has a distorted octahedral 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.
