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, K 2 [Ni(C 16 H 14 N 2 O 2 )] 6 [Ni(CN) 4 ]·6CH 3 OH·2H 2 O, 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.
