Three copper(II) coordination polymers, namely, {[CuL(H 2 O) 2 ] · 4H 2 O} n ( 1 ), [CuL(H 2 O)(DMF)] n ( 2 ), and [CuL(2, 2′‐bipy)(DMSO)] · DMSO ( 3 ) [H 2 L = 2, 2′‐(4, 6‐dinitro‐1, 3‐phenyl‐enedioxy)diacetic acid] were synthesized in different solvents (H 2 O, DMF, and DMSO). X‐ray single crystal diffraction studies show that both complexes 1 and 3 belong to triclinic crystal system and P $\bar{1}$ space group and complex 2 belongs to the monoclinic crystal system and P 2 1 / c space group. In three complexes, all the central Cu II ions coordinate with the ligand, forming a square pyramidal configuration. Both complexes 1 and 2 show similar 1D chain‐like structure and the chains are further connected by hydrogen bonds, forming 3D frameworks. Complex 3 exhibits a 0D structure due to the introduction of the ligand 2, 2′‐bipy. In addition, the luminescence properties of these complexes were investigated.
