Catena-Poly[[[diaqua-copper(II)]-μ-2,2'-{[p-phenyl-enebis(oxymethyl-ene)]bis-(pyridinium-3,1-di-yl)}diacetate] dibromide].

ABSTRACT: 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-phenyl-enebis(oxymethyl-ene)]bis-(pyridine-3,1-di-yl)}diacetic acid with CuBr(2), contains a Cu(II) atom ( 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 inter-actions, forming a two-dimensional network extending parallel to (011).
