The dinuclear title complex, [Ti2(C10H15)2(C6F5O)4O], features two TiIV atoms bridged by an O atom, which lies on an inversion centre. The TiIV atom is bonded to a η5-pentamethylcyclopentadienyl ring, two pentafluorophenolate anions and to the bridging O atom. The environment around the TiIV atom can be considered as a distorted tetrahedron. The cyclopentadienyl ring is disordered over two sets of sites [site occupancy = 0.824 (8) for the major component].

Complex (I) was synthesized by the hydrolysis of Cp*Ti(OC6F5)3. The crystal was obtained by slow evaporation of methylene chloride as a solvent in refrigerator.
The disordered Cp* ring was modeled by splitting the atoms into two components (C1 - C10 and C1A—C10A), the site occupation factors of which refined in a ratio of 0.824 (8):0.176 (8). H atoms were positioned geometrically and refined using a riding model, with C—H distances fixed to 0.96 (methyl CH3), 0.97 (methylene CH2)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. |

Dinuclear titanium complexes containing a cyclopentadienyl ligand have attracted considerable attention in the fields of organometallic catalysis (Noh et al., 2006; Wu et al., 2007; Yoon et al., 2011). Recently, we have reported the facile synthesis of Cp*Ti(OCH2C6F5)3 and Cp*Ti(OC6F5)3 (Cp* = η5-pentamethylcyclopentadienyl) (Lee et al., 2007). We have also reported the X-ray structure of [Ti2(η5-C5Me5)2(OCH2C6F5)4O] (Lee & Kim 2011). In continuation of our systematic studies on bimetallic pentamethylcyclopentadienyltitanium derivative using previously synthesized Cp*Ti(OC6F5)3, the title complex (I) has been investigated.
The title compound (I) is the main product of the reaction of Cp*Ti(OC6F5)3 with water in dichloromethane solution. In (I) (Fig. 1), the dinuclear structure shows two Ti atoms bridged by an oxygen atom, which is lies on inversion centre, Fig. 2 , with approximately C2 symmetry. Ti atom bonded with bridging oxygen atom, a Cp ring and two pentafluorophenolate groups, having distorted tetrahedron geometry.
A disorder of Cp* rings was observed in a ratio of 0.824 (8) and 0.176 (8) for C1—C10 and C1A—C10A, respectively. The Ti—C and Ti—O distances are in the range of 2.337 (16) - 2.400 (11) Å and 1.8184 (11) - 1.854 (2) Å, respectively. The Ti—O—Ti angle is almost linear [180.00 (4) °], which falls within the observed range (154 - 180°) for the previous reported compounds (Wu et al., 2007; Thewalt & Schomburg, 1977; Gowik et al., 1990; Lee & Kim, 2011). Whereas Cp* and phenyl rings are almost perpendicular in [Ti2(η5-C5Me5)2(OCH2C6F5)4O], the Cp* ring and phenyl rings are almost parallel with the dihedral angles of 20.8 (6) ° and 10.2 (6) ° and there is π-π interaction between and Cp ring and phenyl ring (C17—C22) with the perpendicular distance of 3.396 Å.
