Coordination polymer chains built from Cu^II and adipate ions linked by hydrogen bonds to form a three-dimensional framework structure

In the title compound, catena-poly[bis­[(2,2'-bi­pyridine-[kappa]²N,N')(1,1,3,3-tetra­cyano-2-eth­oxy­propenido-[kappa]N)copper(II)]-[mu]₄-hex­anedioato-[kappa]⁶O¹,O^1':O¹:O⁶,O^6':O⁶], [Cu₂(C₉H₅N₄O)₂(C₆H₈O₄)(C₁₀H₈N₂)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 [pi]-[pi] stacking inter­action.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
