摘要

In the title compound, catena-poly[bis[(2,2'-bipyridine-κ2 N,N')(1,1,3,3-tetracyano-2-ethoxypropenido-κN)copper(II)]-μ4- hexanedioato-κ6 O1,O1':O 1:O6,O6':O6], [Cu2(C 9H5N4O)2(C6H 8O4)(C10H8N2) 2]n , the adipate (hexanedioate) dianion lies across a centre of inversion in the space group P . The CuII centre adopts a distorted form of axially elongated (4+2) coordination, and the CuII 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.
