Diethylenetriaminium hexafluoridotitanate(IV) fluoride

J. Lhoste, K. Adil, M. Leblanc and V. Maisonneuve

Abstract top

The title compound, (C6H21N4)[TiF6]F, was synthesized by the reaction of TiO2, tris(2-aminoethyl)amine, HF and ethanol at 463 K in a microwave oven. The crystal structure consists of two crystallographically independent [TiF6]2- anions, two fluoride anions and two triply-protonated tris(2-aminoethyl)amine cations. The Ti atoms are coordinated by six F atoms within slightly distorted octahedra. The anions and cations are connected by intermolecular N-H...F hydrogen bonds.

Comment top

To date, only a few organic-inorganic fluorotitanates were reported. The first compound {(CN3H6)[TiF6]}, described by Calov et al. (1992), is built up from (TiF6) monomers and guanidinium cations. Dadachov et al. (2000) and Tang et al. (2001) reported the synthesis of piperazinium {(C4N2H12)2[Ti2F10]2(H2O)} and piperidinium {[C5H6N2]2(Ti2F11)(H3O)(H20)} fluorotitanates respectively, built up from (Ti2F10)2- or (Ti2F11)3- dimers. As a part of our ongoing investigations in this field (Adil et al., 2006)) we now report the synthesis and structure of the title compound, (I).

The asymmetric unit of (I) consits of two crystallographically independent (TiF6)2- anions, two fluoride anions and two triprotonated tris(2-aminoethyl)amine (tren) cations, all of them located in general positions (Fig. 1). The TiF6 anions form sligthly distorted octahedra and the environnement of both independent anions is different (Table 1). Both TiF6 anions are connected to the cations via N—H···F hydrogen bonding (Figure 2 and Table 2).

The two isolated fluoride anions are also hydrogen bonded to the [H3tren]3+ cations with N—H···F distances ranging from 2.692 (5)Å to 2.791 (5)Å (Figure 2 and Table 2).

Experimental top

The synthetis was performed by using a microwave-assisted route. Crystals were prepared from a mixture of titanium(IV) oxide (79 mg, 1 mmol), tris(2-aminoethyl)amine (0.230 ml, 1.52 mmol), hydrogen fluoride (40%, 0.130 ml, 2.95 mmol) and ethanol (10 ml, 35 mmol). The mixture was transferred into a teflon autoclave installed in a CEM microwave oven at 493 K for 1 hour under a constant pressure of 22 bar. Finally, the solid product was washed with ethanol and dried in air at room temperature to yield colourless paralellepipeds of (I).

Refinement top

A number of mis-measured reflections were omitted from the refinement.

The hydrogen atoms were positioned with idealized geometry (C—H = 0.88-0.97Å, N—H = 0.89Å) and modelled as riding with a group Uiso value refined.

The highest difference is 2.49 Å from H4A. It might be that this peak corresponds to a small amount of water, which cannot be proven. Therefore, this electron density was not considered in the final refinement.

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.
