A new one-dimensional nickel(II) coordination polymer with azido-bridge, [Ni(dpa)(N3)2] Æ H2O 1 (where dpa is the 2,20-dipyridylamine ligand) has been synthesized and crystal structure was determined by single-crystal X-ray diffraction. Complex 1 exhibits a zigzag chain structural arrangement, and the hexa-coordinated Ni(II) ion exhibits a distorted octahedral coordination sphere. The chains topologies are built via three EO and one EE azido bridges. The study of the magnetic properties reveals dominating antiferromagnetic interactions between Ni(II) ions through the EE bridges.
