Two complexes, Zn 4 (C 9 H 5 N 2 O 3 ) 8 (4, 4′‐bipy) 2 ( 1 ) and [Cd(C 9 H 5 N 2 O 3 ) 2 (2, 2′‐bipy)] · 2H 2 O ( 2 ) were synthesized by solvothermal reactions of transition metal nitrates with 5‐nitro‐quinoline‐8‐yl acetate (NQA) under intervention of auxiliary ligands, and characterized by elemental analysis, IR spectroscopy, TGA, and single‐crystal X‐ray diffraction. In complex 1 , every 4, 4′‐bipy adopts a monodentate bridging mode and links two dinuclear asymmetric units, resulting a centrosymmetric neutral tetranuclear zinc complex. Complex 2 is a mononuclear complex, which is alternately arranged to form a 2D network through four kinds of hydrogen bonds. Furthermore, complexes 1 and 2 show excellent luminescent properties in solid state at room temperature.
