Synthesis and characterization of polymeric azido Zn(II) and Ni(II) complexes based on 3-Hydroxypyridine (cas 109-00-2)

The synthesis and structural characterization of two new complexes catena-[Ni(3-O-py)(3-HO-py)2(μ1,3-N3)(H2O)] (1) and catena-[Zn(μ-3-O-py)(μ1,1-N3)] (2), where 3-HO-py = 3-hydroxypyridine, are reported. The complexes were characterized by the elemental microanalyses, IR, and X-ray crystallography and by UV–Vis spectroscopy for complex 1. Single crystal X-ray crystallography revealed the polymeric nature of the complexes: 1 as 1D with a single EE azide bridging, and 2 as 2D with μ(O,O′,N) bridging of the deprotonated 3-O-py anions and di-EO azide groups, respectively. In 1 the neutral and deprotonated 3-hydroxypyridine molecules act only as N-terminal ligands. The emission spectral properties of the Zn(II) complex were investigated.
