    Abstract:
    In the title coordination compound, [Zn(C(12)H(6)O(4))(C(14)H(14)N(4))](n), the two Zn(II) centers exhibit different coordination environments. One Zn(II) center is four-coordinated in a distorted tetrahedral environment surrounded by two carboxylate O atoms from two different naphthalene-1,4-dicarboxylate (1,4-ndc) anions and two N atoms from two distinct 1,4-bis(imidazol-1-ylmethyl)benzene (1,4-bix) ligands. The coordination of the second Zn(II) center comprises two N atoms from two different 1,4-bix ligands and three carboxylate O atoms from two different 1,4-ndc ligands in a highly distorted square-pyramidal environment. The 1,4-bix ligand and the 1,4-ndc anion link adjacent Zn(II) centers into a two-dimensional four-connected (4,4) network. The two (4,4) networks are interpenetrated in a parallel mode.
