Description:
The Nd III coordination compounds [Nd(4-pytza) 3 (H 2 O) 2 ] · 2H 2 O ( 1 ) and [Nd(4-pytza) 2 (H 2 O) 4 ]Cl · 2H 2 O ( 2 ) [H4-pytza = 5-(4-pyridyl)tetrazole-2-acetic acid] were synthesized by reactions of K4-pytza and NdCl 3 · 6H 2 O at different pH values. Single crystal X-ray diffraction analysis reveals that 4-pytza ligands in 1 in a μ 1,3 -COO syn - syn or μ 1,1,3 -COO bridging mode coordinate to two central Nd III atoms to display a dinuclear unit, which is connected by one of these 4-pytza ligands acting in end-to-end bridging mode to form a 1D ladder-like chain. Different from 1 , each 4-pytza in 2 with a μ 1,3 -COO syn - anti bridging mode coordinates to two Nd III atoms to display a 1D zigzag chain. Furthermore, the luminescence properties of 1 and 2 were investigated at room temperature in the solid state.
