Poly[(
6-naphthalene-1,4-dicarboxylato-
6O1:O1':O1':O4:O4':O4')iron(II)]
In the title compound, [Fe(C12H6O4)]n, the FeII atom is coordinated by six O atoms from six symmetrically equivalent naphthalene-1,4-dicarboxylate ligands in a strongly distorted octahedral geometry. These octahedra are connected via common edges into chains that elongate along the a axis, with Fe
Fe distances of 2.9712 (4) and 2.9724 (4) Å. The chains are linked via the naphthalene-1,4-dicarboxylate ligands into a three-dimensional coordination network.
A mixture of FeSO4.7H2O (0.139 g, 0.5 mmol),
naphthalene-1,4-dicarboxylic acid (0.108 g, 0.5 mmol), KOH (0.112 g, 1 mmol)
and water (5 ml) was transfered into a glass tube and heated to 423 K for 4 d.
On cooling, yellow needle crystals of the title
compound were obtained.
H atoms were positioned geometrically and refined as riding atoms,
with C—H = 0.95 Å and with Uiso(H) = 1.2Ueq(C).

The structure determination of the title compound was performed as a part of a project on the synthesis of new metal–organic frameworks. In this project we have reacted iron(II) sulfate with naphthalene-1,4-dicarboxylic acid in potassium hydroxide and water, which leads to the formation of a naphthalene-1,4-dicarboxylate iron(II) coordination polymer.
The title compound is isostructural to the manganese(II) and cobalt(II) complexes of naphthalene-1,4-dicarboxylate (Maji et al., 2005). In the title compound, the FeII atom is surrounded by six O atoms from six crystallographically equivalent naphthalene-1,4-dicarboxylate ligands in a distorted octahedral coordination environment (Fig. 1 and Table 1). The Fe atoms are linked by O atoms of the carboxylate groups in a µ3-O:O':O' mode into chains, which elongate along the a axis (Fig. 2). Within these chains the Fe coordination octahedra are connected via common edges. These chains are connected by the naphthalene-1,4-dicarboxylate ligands into a three-dimensional network.
