Descripción
Sumario:The title centrosymmetric coordination polymer, {[Cu(C(22)H(20)N(2)O(6))(H(2)O)(2)]Br(2)}(n), formed by the reaction of the flexible double betaine ligand 2,2′-{[p-phenyl­enebis(oxymethyl­ene)]bis­(pyridine-3,1-di­yl)}diacetic acid with CuBr(2), contains a Cu(II) atom ([Image: see text] 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).
