Bis[4-(4-pyridyl)pyridinium] (4-carboxypyridine-2,6-dicarboxylato-
3O2,N,O6)(pyridine-2,4,6-tricarboxylato-
3O2,N,O6)ferrate(III) trihydrate
In the title salt, (C10H9N2)2[Fe(C8H2NO6)(C8H3NO6)]·3H2O, the FeIII atom is O,N,O'-chelated by dianionic and trianionic ligands in a slightly distorted octahedral coordination geometry. The cations and ferrate anions are linked into a layered structure; the layers are connected through the uncoordinated water molecules into a hydrogen-bonded three-dimensional supramolecular structure. One of the uncoordinated water molecules is disordered around an inversion centre and was refined with half-occupancy for each position.
Pyridine-2,4,6-tricarboxylic acid (H3ptc) was synthesized by oxidization of
pyridine-2,4,6-trimethyl with potassium permanganate according to a literature
(Syper et al., 1980).A mixture of H3ptc (0.110 g, 0.05 mmol),
FeCl2.6H2O (0.126 g, 0.10 mmol), 4,4'-bpy (0.156 g, 0.10 mmol), 16 ml H2O and seven drops of triethylamine were loaded into a 23 ml Teflon-lined
stainless autoclave, which was heated up to 120 °C, at which temperature the
reactor was held for 3 days, and then cooled to room temperature. The reaction
yielded brown block crystals of (I) in a yield of 10.32% based on
FeCl2.6H2O. IR spectroscopic analysis (KBr, υ/cm-1): 3535(m),
3436(m), 1674(s), 1612(m), 1573(w), 1492(m),
1330(s), 1195(s), 1076(w), 1043(m), 1006(m),
931(w), 813(s), 779(w), 748(m), 771(w), 678(w).
H atoms bonded to C atoms were placed in geometrically calculated position and
were refined using a riding model, with Uiso(H) = 1.2
Ueq(C). H atoms bonded to N and carboxyl O atoms were palced in
geometrically calculated position and were refined using a riding model, with
Uiso(H) = 1.5 Ueq(C). The water H atoms were found in a
difference Fourier synthesis and were refined using a riding model, with the
O—H distances fixed as 0.85±0.01 Å and with Uiso(H) values set
at 1.5 Ueq(O). The O13 was disordered into two positions and treated as
each occupation of 50%.

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

Great interest has been focused on the rapidly expanding field of supramolecular chemistry and crystal engineering of the coordination polymers in reacent years because of their intriguing network topoloies as well as their potential application as functional materials in many areas such as separations and catalysis, gas storage, and magnetism (Kaneko et al., 2007; Li et al., 2008; Lin et al., 2009). Pyridine-2,4,6-tricarboxylic acid (H3ptc) is a good building block for constructing supramolecular complex, which can link 3 d, 4f and 3 d-4f metal ions. However, plenty of researches have focused on the supramolecular chemistry and coordination polymers which only include single carboxylic acid ligands, whereas the studies and syntheses about the mixed-ligand compounds which contain two or two more ligands seem comparatively limited (Ghosh & Bharadwaj, 2006; Lin et al., 2007). In this paper, we report the crystal structure of the title compound prepared from FeCl2.6H2O, H3ptc and 4,4'-bipyridine (4,4'-bpy).
The structure of title compound consists of [Fe(Hptc)(ptc)]2- anions, Hbpy+ cations and lattice water molecules. In the anion, Hptc2- and ptc3- ligands are bound to one Fe(III) ion through pyridine N and deprotonated carboxylate O atoms at 2- and 6-positions, leading to a distorted octahedral geometry around the metal. The carboxylic groups at the 4-position of ptc ligands are uncoordinated. [Fe(Hptc)(ptc)]2- anion is connected into two-dimensional layers through H-bonding interactions (Talbe 2). In the cationic part, the Hbpy+ ligands are not coordinated to metal ions. They are connected by N—H···N hydrogen-bonding and π-π stacking interactions to form another two-dimensional layers. The layers are futher linked into three-dimensional supramolecular structure by the intermolecular hydrogen bond interaction.
