Synthesis and characterization of two 1D polymeric zinc(II) azido complexes derived from pyridine-N-oxide co-ligands

The synthesis and structural characterization of two new polymeric zinc(II) azido complexes with pyridine-N-oxide derivative co-ligands, namely catena-[Zn(4-methylpyridine-N-oxide)(μ1,1–N3)2] (1) and catena-{[Zn2(μ2-isonicotinato-N-oxide)2(μ1,1–N3)2(H2O)3](H2O)} (2) are reported. Single crystal structure determination revealed the penta-coordinated geometry of the Zn(II) centers in the polymeric chains of 1 with di-EO azido bridging mode, whereas five and six coordination modes around Zn(II) centers are observed in complex 2, and the 1D system is formed via alternating single EO-azide and μ(O,O′)-bridging carboxylate group of the isonicotinato-N-oxide molecules. The solid state luminescence properties of 1 were examined.
