Dipotassium hexakis({2,2'-[ethane-1,2-diylbis(nitrilo­methyl­idyne)]diphenolato}nickel(II)) tetracyano­nickelate(II) methanol hexasolvate dihydrate

In the crystal structure of the title compound, K₂[Ni(C₁₆H₁₄N₂O₂)]₆[Ni(CN)₄]·6CH₃OH·2H₂O, at 180 K, the nickel(II)-Schiff base units form dimeric associations across inversion centres. The K⁺ cations occupy distorted octahedral sites surrounded by O atoms of the nickel(II)-Schiff base units, and the centrosymmetric [Ni(CN)₄]^2- anions participate in a two-dimensional hydrogen-bond network that includes the uncoordinated methanol and water molecules.
