The reaction of Cd(ClO 4 ) 2 ·6H 2 O with the tetradentate tripod amine BPQA (bis(2-methylpyridyl)-2-methylquinolyl-amine) afforded the mononuclear complex [Cd(BPQA)(N 3 ) 2 ] ( 1 ), whereas its reaction with the bidentate amines Et 2 Meen (N,N-diethyl-N′-methylethylenediamine) and DMP (2-(3,5-dimethylpyrazol-1-ylmethyl)pyridine) resulted in the formation of different bridged-azido polymeric 2D- and 1D-chains [Cd 2 (Et 2 Meen) 2 (μ 1,1 -N 3 ) 2 (μ 1,3 -N 3 ) 2 ] n ( 2 ) and [Cd(DMP)(μ 1,1 -N 3 ) 2 ] n ( 3 ), respectively. The reaction of Zn(ClO 4 ) 2 ·6H 2 O with DMP led to the isolation of the doubly bridged EO-azido dinuclear complex [Zn(DMP)(μ 1,1 -N 3 )(N 3 )] 2 ( 4 ). The four complexes have been structurally characterized by elemental microanalyses, IR spectroscopy and by single crystal X-ray crystallography. The luminescence properties of [Cd(BPQA)(N 3 )] ( 1 ) complex and its ligand, BPQA were investigated, where the complex revealed strong fluorescence enhancement.
