A 2‐D Grid Coordination Polymer with an In‐plane and Out‐of‐plane Structure Bridged by Pyrazine Spacers

A 2-D grid copper(II) complex [Cu(μ3-H2dpzpda)(N3)]n(ClO4)n (2) has been synthesized and structurally characterized. The copper atom in the complex is six-coordinated in an octahedral geometry. The azide anions coordinated with copper in a 1-end form, and the perchlorate anions are not coordinated to copper centers. The structure shows an orthogonal overlap of orbitals through the bridging pyrazine. Extensive hydrogen bonds were observed in 2D networks. Magnetic studies indicate the presence of very weak antiferromagneic coupling between copper(II) ions.
