A 2D copper(Ⅱ) coordination polymer [Cu(anol)(μ_(1,3)-N_3)]_n containing 2-aminoethanol (anol) and azide bridging ligands, has been synthesized and characterized by single crystal X-ray diffraction and magnetic susceptibility. Crystal data for [Cu(anol)(μ_(1,3)-N_3)]_n: monoclinic system, space group P2_1/n, a=0.838 06(17) nm, b=0.773 55(15) nm, c=0.853 49(17) nm,β= 113.26(3)°, V=0.508 32(17) nm~3, Z=4. The 2-aminoethanol ligands are coordinated on the bidentate coordination mode with a nitrogen atom of the amino and an oxygen atom of the hydroxyl. The two Cu(Ⅱ) ions are bridged by the two oxygen atoms of 2-aminoethanols and the binuclear [Cu_2(anol)_2] unit are formed. The binuclear units are linked through EE-azide groups and resulting a 2D network. Variable temperature magnetic susceptibility measurements in the temperature range 2～300 K reveal the existence of antiferromagnetic couplings in the network.
