Many efforts have been devoted to the study of transition metal azide complexes due to
their structural diversities and attractive magnetic properties [1]. The bridging small
pseudohalides, especially azide ions, are good condidates for magnetic exchange interaction
between paramagnetic metal centers [2]. The azido bridges are bounded to the metal ions in
various coordination modes, which the most common of them are end-to-end and end-on [3].
In this project, we report the syntheses, characterization and spectroscopic properties of Cd(II)
complex with salophen-type and azide ligands. The ligand is prepared from the condensation
reaction between 4-chloro-1,2-diaminobenzene and salicylaldehyde in ethanol. The complex
is obtained from the reaction between 4-chlorosalophen, NaN3 and Cd(CH3COO)2.H2O in
methanol solvent. The FT-IR spectrum of the complex displays the characteristic bands of
azide and imine groups. The absorption of –C=N– stretching vibration of imine groups in
complex occurs as a strong band at 1616 cm-1. This complex exhibits the sharp band at 2058
cm-1, which is attributable to the coordination of azide ligand to the Cd )II( ion.
