Three one-dimensional azido-bridged metal(II) complexes, [Ni-2(4-azpY)(4)(mu(1.1)-N-3)2(mu(1.3)-N-3)(2)]n, (1), [CO2 (4-azpY)4(mu(1.1)-N-3)2(mu(1.3)-N-3)(2)]n (2), and [Cd-2(4-azPY)4(mu 1.1-N-3)2(mu(1,3)-N-3)(2)](n). (3), (4-azpy = 4-azidopyridine) were synthesized and characterized by UV-Vis, IR spectroscopy and by single crystal diffraction. The three iso-structural complexes exhibit distorted octahedral geometry around the metal(II) centers, terminal 4-azidopyridine ligands in trans-dispositions and alternating doubly bridged EO- and doubly bridged EE-azido ligands giving rise to polymeric 1-D systems. The asymmetric nature of the azide groups is increasing from EE-via EO- to covalent bonded N3-group in the 4-azidopyridine ligand. The magnetic properties of complexes 1 and 2 are reported.
