In the title compound, catena-poly[bis[(2,2'-bipyridine-κ(2)N,N')(1,1,3,3-tetracyano-2-ethoxypropenido-κN)copper(II)]-μ4-hexanedioato-κ(6)O(1),O(1'):O(1):O(6),O(6'):O(6)], [Cu2(C9H5N4O)2(C6H8O4)(C10H8N2)2]n, the adipate (hexanedioate) dianion lies across a centre of inversion in the space group P1. 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.
