The Cu<sup>II</sup> centre adopts a distorted form of axially elongated (4+2) coordination, and the Cu<sup>II</sup> 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<sup>II</sup> 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.</p> </abstract>
