Comment top

In recent years organochromium complexes have received more and more attentions as heterogenous or homogeneous catalysts for olefin polymerization (MacAdams et al., 2005; Smith 2005; Jones et al., 2005). Previously, much research effort has been dedicated in the synthesis of half-sandwich chromium complexes as model systems for the unipol family of silica-supported chromium catalysts which can produce high density polyethylene (Theopold et al., 1998; Karol et al., 1972; Cole & Gibson, 1994). Recently, a number of non-cyclopentadienyl ligand have been investigated with a view to synthesizing high active, single site or well define olefin polymerizaton catalysts, which have provided new opportunities for the production of polymers with tailored structures and novel properties. Hence, our work aimed to synthesize the new chromium complex with β-diketiminato ligand. Here, we report the synthesis and structure of the first such species, [(Ph)NC(Ph)C(H)C(CH3)OCr]2(µ-Cl)2[µ-O(CH3)CC(H)(Ph)CN(Ph)] Cl.2C7H8.

The title complex crystallized in the monoclinic system and the structure consists of three six-membered chelate rings, as illustrated in Figure 1. Two unsymmetric chromium centres are in a distorted octahedral environment held together by one oxygen and two chloride bridges. The two Cr atoms are in distinct stereochemical environment. Atom Cr1 is coordinated by two β-diketiminato ligands, two bridging C1 (Clb) atoms and one bridging O atom (Ob); atom Cr2 is coordinated by one β-diketiminato ligand, one Cl atom, two Clb atoms and one Ob atom. In each chelate ring the bite angle is near optimal, the respective O—Cr—N angles being in the range 88.80 (10) to 99.22 (10)°.

The range of the Cr—O, Cr—N and Cr—Cl bonds lengths (Table 1) are 1.890–2.138, 2.016–2.019 and 2.3954–2.4145 Å, respectively. These are comparable to the bond lengths for the reported mononuclear chromium complexes with salicylaldiminato ligands (Gibson et al., 2000), which have Cr—O bond length of 1.947 (3) Å, Cr—N bond length of 2.074 (4) Å and Cr—Cl bond length of 2.320 (1) Å. In addition, the Cr—Cl distance for Cr1 atom bonded to one terminate Cl is somewhat shorter than those for Cr2 bonded to two Clb. The Cr—O distances for atoms bonded to Ob are longer than those for Cr bonded to β-diketiminato ligand.

Experimental top

Reaction of CrCl3(THF)3 with equivalent lithium salt of β-diketiminate in dried tetrahydrofuran for 20 h at ambient temperature followed by evaporation of the solvent in vacuum to yield a crude product. To the crude product was added dried CH2Cl2, and the mixture was stirred for 10 min and then filtered. The filtrate was evaporated in vacuum to afford a solid residue, which was dissolved by toluene and layered with n-hexane. The brown crystals of the title compound were obtained in 62% yield.

Refinement top

H atoms were positioned geometrically (C—H = 0.93–0.96 Å) and refined in the riding-model approximation, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C). For one of the toluene molecules, atoms C56–C62 were refined isotropically to avoid abnormal deformation of the displacement ellipsoids.

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.
