title: Bis(acetyl-acetonato-κ(2)O,O')bis-(pyridine-κN)nickel(II) dihydrate.
abstract: The title compound, [Ni(C(5)H(7)O(2))(2)(C(5)H(5)N)(2)]·2H(2)O, crystallizes with two half-mol-ecules in the asymmetric unit. The Ni(II) ion of each unique complex mol-ecule lies on an inversion centre and has an octa-hedral coordination geometry. The crystal structure features weak O-H⋯O hydrogen bonds, which form chains running parallel to the a axis.
