In the title compound, catena ‐poly[bis[(2,2′‐bipyridine‐κ 2 N , N ′)(1,1,3,3‐tetracyano‐2‐ethoxypropenido‐κ N )copper(II)]‐μ 4 ‐hexanedioato‐κ 6 O 1 , O 1′ : O 1 : O 6 , O 6′ : O 6 ], [Cu 2 (C 9 H 5 N 4 O) 2 (C 6 H 8 O 4 )(C 10 H 8 N 2 ) 2 ] n , the adipate (hexanedioate) dianion lies across a centre of inversion in the space group P . The Cu II centre adopts a distorted form of axially elongated (4+2) coordination, and the Cu II and adipate components form a one‐dimensional coordination polymer from which the 2,2′‐bipyridine and 1,1,3,3‐tetracyano‐2‐ethoxypropenide components are pendent, and where each adipate dianion is bonded to four different Cu II centres. The coordination polymer chains are linked into a three‐dimensional framework structure by a combination of C—H...N and C—H...O hydrogen bonds, augmented by a π–π stacking interaction.
