    By changing metal ions in the presence of N2O2-chelating Schiff-base ligand sal2hn [sal2hn = N,N'-bis(salicylidene)-1,2-diaminocyclohexane] and a large excess of NaN3, tetranuclear copper(II) complex [Cu4(μ-sal2hn)2(μ1,1-N3)2(N3)2] (1) and 1D chain coordination polymer of cobalt(III) complex {Na[Co(μ-sal2hn)(μ1,1-N3)(N3)(H2O)(μ-O)}n(2) have been successfully obtained. Single-crystal X-ray analyses revealed that in complex 1 the copper(II) ions are bridged alternately by azido and phenoxo-sal2hn ligands, while in complex 2 the cobalt(III) and sodium ions are bridged alternately by azido and phenoxo-sal2hn ligands and sodium ions are linked together by O atoms to form polymeric chain.
