2-(2-Ammonio­ethyl)pyridinium hexa­chloridorhenate(IV)

Abstract

In the title anti­ferromagnetic material, (C7H12N2)[ReCl6], the Néel temperature is observed at 5 K. The salt is stabilized by an extensive network of N—H(...)Cl and C—H(...)Cl hydrogen bonds, where hydrogen-bonded anion chains and characteristic cation–anion motifs are present. Similar systems play an important role in crystal engineering as hydrogen bonds that can transmit magnetic inter­actions.

Comment

Rhenium(IV) salts with ammonium cations are known and have been described previously (Sawusch et al., 1999, Mrozinski et al., 2002, Kochel 2004). Some of the hexachlororhenates(IV) have interesting properties, e.g. as semiconductors (Kepert et al., 1997). The title salt comprises of 2-(2-aminoethyl)pyridinium cations and ReCl62- anions. Figure 1 illustrates the two independent formula units of compound (1). The anion bond lengths are comparable to those for other anions of this type (see table in supplementary material). The crystal structure is stabilized by an extensive network of N—H···Cl and C—H···Cl hydrogen bonds (Fig. 2). Almost all amino H atoms bonded to the organic cation participate in hydrogen bonds as donors. Some of the hydrogen bonds e.g. N3—H3···Cl12, N3—H3···Cl1 are bifurcated. The hydrogen bonding parameters are included in Table 1. The use of small low-symmetry ammonium cations enable these ions to occupy general positions, so that the Re···Re distances are much smaller. In the crystal packing, two types of arrangement of molecules may be distinguished: in the [100] direction a layered arrangement [alternating anions and cations] is observed, while in the [010] direction, and the whole is stabilized by a network of hydrogen bonds. The shortest Re1···Re1i distance is 7.371 (2)Å [symmetry code: (i) x - 1,y,z]. The magnetic susceptibility of (1) is measured in the temperature range from 2 to 300 K under the applied magnetic field of 0.5 T (Figure 3). The χmT values decrease slowly upon cooling. The effective magnetic moment of 3.55 B. M. at 300 K is reduced in comparison to the spin-only value (3.87 uB), and in 2 K is 0.84 B. M. Generally, the complex shows linear χmversus T behaviour in the 300–50 K range with C = 1.70 cm3 mol-1 K, Q = -14.5 K. The susceptibility curves exhibit the maximum at 5 K, indicating directly the presence of antiferromagnetic interactions.

The χmT at 300 K is 1.58 cm3 Kmol-1 and this value is expected for an isolated Re(IV) ion. As the temperature is lowered, χmT decreases, and the value is 0.896 cm3 Kmol-1 at 2 K. This behaviour indicates antiferromagnetic interactions between the Re(IV) ions. The occurrence of antiferromagentic interactions could be related to aspects of the structure. The smallest Re—Re distance is 7.371 (2) Å, and a substantial value, however, there are numerous hydrogen bonds in the crystal structure, forming a three-dimensional framework. The hydrogen bonds stabilize the crystal structure layered arrangement. Probably the hydrogen bonding system enhances the magnetic exchange interactions. Future perspectives concerning this work will involve further studies on hexachlororhenates(IV) as potential materials used as semiconductors.

Experimental

(NH4)2ReCl6 (0.15 g) was dissolved in water (50 ml) with concentrated HCl (2 ml) and the mixture was heated under reflux at 340 K. After 30 min, 2-(2-aminoethyl)pyridine (0.25 g) was added. The mixture was heated for further 5 h. After cooling, the yellow precipitate was filtered off and washed with ethanol. Crystals for X-ray study were obtained by slow evaporation of an aqueous solution of the yellow precipitate with addition of 1 ml HCl solution. The crystals are in the form of plates. For data collection a small plate was used, cut from a larger one.

The magnetic measurements of polycrystalline samples were carried out over the temperature range of 2–300 K using a Quantum design SQUID-Based Magnetometer MPMSXL5. The SQUID magnetometer was calibrated with a palladium rod sample, for which the gram susceptibility was assumed as 5.30 x 10–6 cm3g-1 at 293 K (National Bureau of Standards, USA). The susceptibility measurements were made in the field of 0.5 T. Corrections were done for the diamagnetic response of the sample rod and of the sample using Pascal's constants (Koenig, 1966).

Refinement

The structure (1) was solved by direct methods using SHELXS97 software (Sheldrick, 2008) and refined using SHELXL97 (Sheldrick, 2008). In case of (1) DFIX restraints were used for all C—H bond lengths (0.93–0.97 Å with the allowed deviation of 0.002 Å. All H atoms were refined with Ueq set at 1.2 Ueq (parent atom). H atoms associated with N atoms were located on difference maps and then freely refined. In the final difference maps the following highest peaks were found: for (1) the maximum of -1.30 and 2.07 e/Å3 at 0.68 and 0.78 Å from the Re(2) atom

Special details

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.
