Abstract

A novel two-dimensional (2D) copper(II) coordination polymer, [CuL(N₃)₂]_n (1) (L = 2-aminomethylpyridine), has been synthesized and characterized by elemental analysis, IR, X-ray crystallography and magnetic susceptibility. The complex crystallizes in space group P2₁/c with a = 9.940(3), b = 8.057(2), c = 12.310(4) Å, β = 104.119(4)°, V = 956.1(5) Å³, Z = 4, with final R = 0.0543. The copper(II) ion in 1 is coordinated through two N atoms of the ligand L and four N atoms from the azido ligands in an elongated octahedron. The polymer consists of (6, 3) layers in which alternate double end-on (EO) and single end-to-end (EE) N₃^- bridging modes are found. The pyridine rings coming from adjacent layers are stacked by π-π interactions. Magnetic measurements reveal a weak antiferromagnetic exchange between copper(II) ions in 1.
