Poly[aqua[μ(2)-1,2-bis­(imidazol-1-yl­methyl)benzene-κ(2) N (3):N (3′)](μ(2)-5-bromo­benzene-1,3-dicarboxyl­ato-κ(3) O (1),O (1′):O (3))nickel(II)]

In the two-dimensional title coordination polymer, [Ni(C(8)H(3)BrO(4))(C(14)H(14)N(4))(H(2)O)](n), the Ni(II) atom adopts a distorted octa­hedral geometry, being ligated by three O atoms from two different 5-bromo­benzene-1,3-dicarboxyl­ate ligands, two N atoms from two 1,2-bis­(imidazol-1-ylmeth­yl)benzene ligands and one coordinated water mol­ecule. The Ni atoms are bridged by the 5-bromo­benzene-1,3-dicarboxyl­ate ligands, forming chains, which are further linked by 1,2-bis­(imidazol-1-ylmeth­yl)benzene, generating a layer structure parallel to (001).
