A new one-dimensional chain complex [Cu(N3)2(C6H8N2)]n (C6H8N2=(2-aminomethyl)pyridine) has been synth-esized and characterized by EA, FTIR and X-ray single-crystal structure analysis. The complex crystallizes in triclinic space group P1, with a=0.690 1(2) nm, b=0.825 1(3) nm, c=0.995 3(3) nm, α=67.154(5)°, β=72.898 (5)°, γ=65.462 (5)°, V=0.469 1 (3) nm3, Z=2. Magnetic susceptibility measurement indicates that there is a weak ferro-magnetic exchange coupling between Cu(Ⅱ) ions. CCDC: 686151.
