Deskripsi
The title centrosymmetric coordination polymer, {[Cu(C22H20N2O6)(H2O)2]Br2}n, formed by the reaction of the flexible double betaine ligand 2,2′-{[p-phenylenebis(oxymethylene)]bis(pyridine-3,1-diyl)}diacetic acid with CuBr2, contains a Cu(II) atom (overline1 symmetry) which is surrounded by two water molecules and bridged by two anions in a square-planar coordination. In the crystal, polymeric zigzag chains are linked via O—H...Br interactions, forming a two-dimensional network extending parallel to (011).
