چکیده
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).

In the title compound, {[Cu(C(10)H(14)N(4))(2)(H(2)O)(2)](NO(3))(2)}(n), the Cu(II) ion lies on an inversion center and is six-coordinated in an octa-hedral environment by four N atoms from four different 1,1'-butane-1,4-diyldiimidazole ligands and two O atoms from the two water mol-ecules. Bridging by the ligands results in a ribbon structure. Adjacent ribbons are linked to the nitrate anions ...
