Syntheses and Structures of Three New Copper(II) Coordination Polymers Involving 2, 2-(4, 6-Dinitro-1, 3-phenylenedioxy)­diacetic Acid

Three copper(II) coordination polymers, namely, {[CuL(H2O)2]·4H2O}n(1), [CuL(H2O)(DMF)]n(2), and [CuL(2, 2′‐bipy)(DMSO)]·DMSO (3) [H2L = 2, 2′‐(4, 6‐dinitro‐1, 3‐phenyl‐enedioxy)diacetic acid] were synthesized in different solvents (H2O, DMF, and DMSO). X‐ray single crystal diffraction studies show...

Description
Summary:Three copper(II) coordination polymers, namely, {[CuL(H2O)2]·4H2O}n(1), [CuL(H2O)(DMF)]n(2), and [CuL(2, 2′‐bipy)(DMSO)]·DMSO (3) [H2L = 2, 2′‐(4, 6‐dinitro‐1, 3‐phenyl‐enedioxy)diacetic acid] were synthesized in different solvents (H2O, 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 P21/c space group. In three complexes, all the central CuII 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.
