摘　　要：Hydrothermal reactions of Cu (II) ace-tate, 2,2′-bipyridyl (bpy) with 5-nitroisophthalic acid (H2NIPH) resulted in a new coordination polymer [Cu(NIPH)(bpy)] 1. Single crystal X-ray diffraction experiment indicates that 1 possesses a single helix- like chains, of which Cu atoms are coordinated by NIPH ligands and bpy ligands. Compound 1 crystal-lizes in the space group P2(1)/c, a = 0.955(19) nm, b = 1.259(3) nm, c = 1.3737(3) nm, β = 95.13(3)°, V = 1.6455(6) nm3 and Z = 4. The TGA analysis shows that 1 has no remarkable weight loss up to 284℃, as a result of its high thermal stability. Magnetic meas-urements indicate an antiferromagnetic behavior of compound 1.Hydrothermal reactions of Cu （Ⅱ） acetate, 2,2＇-bipyridyl （bpy） with 5-nitroisophthalic acid （H2NIPH） resulted in a new coordination polymer [Cu（NIPH）（bpy）] 1.
