Bis(acetyl­acetonato-κ²O,O′)bis­(pyridine-κN)nickel(II) dihydrate

The title compound, [Ni(C₅H₇O₂)₂(C₅H₅N)₂]·2H₂O, crystallizes with two half-mol­ecules in the asymmetric unit. The Ni^II ion of each unique complex mol­ecule lies on an inversion centre and has an octa­hedral coordination geometry. The crystal structure features weak O—H...O hydrogen bonds, which form chains running parallel to the a axis.
