Tris(phenanthroline-²N,N')nickel(II) dibromosuccinate heptahydrate

D.-X. Li, D.-J. Xu and Y.-Z. Xu

Abstract: The crystal structure of the title compound, [Ni(C₁₂H₈N₂)₃](C₄H₂Br₂O₄)·7H₂O, consists of discrete nickel(II) complex cations, dibromosuccinate dianions and uncoordinated water molecules. The Ni^II atom is surrounded by three phenanthroline ligands in a distorted octahedral geometry. The overlapped arrangement and short face-to-face distances of 3.525  (12) and 3.369  (5)  Å between parallel phen planes of neighboring complexes indicate - stacking. The dibromosuccinate dianions are located on inversion centers and are linked to uncoordinated water molecules via hydrogen bonds.
