Diaquabis(4-hydroxybenzoato-O)(1,10-phenanthroline-²N,N')cobalt(II) monohydrate

J.-R. Su, J.-M. Gu and D.-J. Xu

Abstract: The title complex, [Co(C₇H₅O₃)₂(C₁₂H₈N₂)(H₂O)₂]·H₂O, displays a distorted octahedral coordination geometry about the Co^II atom, involving two 4-hydroxybenzoate anions, one 1,10-phenanthroline (phen) molecule and two water molecules. The face-to-face distance of 3.420 (5) Å between partially overlapped parallel phen rings reflects a - stacking interaction between neighboring Co^II complex molecules. A network of O-HO hydrogen bonds helps to stabilize the crystal packing.
