The title compound, {[Fe(NCSe)2(C12H12N2)(H2O)2]·2C12H12N2·2H2O}n, was obtained by the reaction of iron(II) sulfate hepta­hydrate and potassium seleno­cyanate with 1,2-bis­(pyridin-4-yl)ethane (bpa) in water. The FeII cation is coordinated by two N-bonded seleno­cyanate anions, two water mol­ecules and two 1,2-bis­(pyridin-4-yl)ethane (bpa) ligands in a slightly distorted octa­hedral geometry. In addition, two non-coordinating bpa mol­ecules and two water mol­ecules are present. The FeII cation is located on a center of inversion while the coordinating bpa ligand is located on a twofold rotation axis. The FeII cations are linked by the bpa ligands into chains along the b-axis direction, which are further connected into layers perpedicular to the c axis by O—H⋯N and O—H⋯O hydrogen bonds to the non-coordin­ating bpa and the water mol­ecules. The crystal studied was twinned by pseudo-merohedry (180° rotation along c*; contribution of the minor twin component 3.7%).

Comment top

In our recent work we have reported on the synthesis and characterization of cobalt(II) and iron(II) selenocyanate coordination polymers that show coexistence of metamagnetism and a slow relaxation of the magnetization (Boeckmann & Näther, 2011; Wöhlert et al., 2012 and Boeckmann et al., 2012). These compounds can be prepared by thermal decomposition of suitable precursor compounds that contain volatile ligands like e.g. water in hydrates and therefore, such compounds are of extreme importance for our project. In the course of these investigations we obtained such a precursor based on 1,2-bis(pyridin-4-yl)ethane (bpa), which was characterized by single-crystal X-ray diffraction.

In the crystal structure of the title compound Fe(NCSe)2(C12H12N2)(H2O)2]n.2C12H12N2.2H2O solvate each FeII cation is coordinated by two N-bonded selenocyanate anions, two water molecules and two bpa ligands (Fig. 1). The FeN4O2 octahedra are slightly distorted with distances in the range of 2.071 (4) Å to 2.344 (4) Å. The angles arround the FeII cations are in the range of 86.91 (16) ° to 93.09 (16) ° and of 180 ° (Tab. 1). Each FeII cation is located on a center of inversion while the coordinating bpa ligand is located on a twofold rotation axis. The iron(II) cations are connected by the bpa ligands into one dimensional polymeric chains, which elongate in the direction of the crystallographic b-axis (Fig. 2). These chains are linked by intermolecular O—H···N and O—H···O hydrogen bonding into layers by non-coordinating bpa ligands and water molecules perpedicular to c (Fig. 2, Tab. 2).

Experimental top

FeSO4×7H2O, KNCSe and 1,2-bis(pyridin-4-yl)ethane were obtained from Alfa Aesar. All chemicals were used without further purification. 0.15 mmol (43 mg) FeSO4×7H2O and 0.2 mmol (28 mg) KNCSe were reacted with 0.6 mmol (109 mg) 1,2-bis(pyridin-4-yl)ethane in 1 ml water. Red single-crystals of the title compound were obtained after three days.

Refinement top

All H atoms were positions with idealized geometry and were refined isotropically with Uiso(H) = 1.2 Ueq(C) using a riding model with C—H = 0.93 Å and C—H2 = 0.97 Å. The O—H hydrogen atom were located in a difference map, their bond lengths were set to an ideal value of 0.82 Å, and finally they were refined using a riding model with Uiso(H) = 1.5 Ueq(O). Twinning by pseudo-merohedry of the crystal by a 180° rotation along c* was taken into account, using a twin matrix (-1 0 0 0 -1 0 1 0 1; BASF parameter: 0.03696) which lowered the R value from 6.16 to 4.5%.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
