The title compound, [Ti(C4H9N)Cl(C5H5N)2(C7H11N2)]·C7H8, has a mononuclear structure featuring a six-coordinate distorted octa­hedral titanium(IV) centre. The central TiIV ion is coordinated by two N atoms from a dimeth­yl(1H-pyrrol-2-ylmeth­yl)amine mol­ecule, two N atoms from two pyridine mol­ecules, one N atom from a N-tert-butyl­imido ligand and one Cl atom.

Comment top

Over the last two decades, the chemistry of titanium–imido complexes has received considerable attention (Wigley, 1994). It has been shown that these complexes can be utilized in a wide variety of stoichiometric and sometimes catalytic coupling reactions with unsaturated substrates. A general entry point to new titanium–imido chemistry is gained via the readily prepared synthons [Ti(NR)Cl2(py)3] (R = tBu or Aryl) (Mountford, 1997).

The title compound, (I), was prepared by combining equimolar amounts of Ti(NtBu)Cl2py3 with Lidap [N,N-dimethyl-(1-Li-pyrrol-2-yl)methanamine] in toluene. It possesses a mononuclear structure featuring a six-coordinate octahedral titanium(IV) centre.

Experimental top

To a near-frozen solution of Ti(NtBu)Cl2py3 (Mountford, 1997) (1.234 g, 2.9 mmol) in toluene (10 ml), Lidap [N,N-dimethyl-(1-Li-pyrrol-2-yl)methanamine] (376.1 mg, 2.9 mmol) in toluene (10 ml) was added dropwise. After stirring at room temperature for 12 h, the resulting solution was filtered to remove solids. Volatiles were removed from the solution under reduced pressure to yield the orange crude product, which was washed with toluene and filtered to remove a trace amount of LiCl, then recrystallized from toluene (yield 920 mg, 60%).

Refinement top

All H atoms were positioned geometrically and refined using a riding model (including free rotation about the ethanol C—C bond), with C—H = 0.95–0.99 Å and with Uiso(H) = 1.2 (1.5 for methyl groups) times Ueq(C).

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.
