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

Abstract

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(2,2Јbipy)(DMSO)]·DMSO (3) [H 2 L = 2,2Ј-(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 P1 space group and complex 2 belongs to the monoclinic crystal system and
