The title complex, [Hf(C29H41N2)Cl3], was synthesized from HfCl4 and HC[C(Me)N(iPr2C6H3)]2Li(Et2O) in toluene. The structure is isotypic with those of TiIV and ZrIV complexes reported previously [Nikiforov et al. (2007[Nikiforov, G. B., Roesky, H. W., Jones, P. G., Oswald, R. B. & Noltemeyer, M. (2007). Dalton Trans. pp. 4149-4159.]). Dalton Trans. pp. 4149–4159; Kakaliou et al. (1999[Kakaliou, L., Scanlon, W. J., Qian, B. S., Baek, S. W., Smith, M. R. & Motry, D. H. (1999). Inorg. Chem. 38, 5964-5977.]). Inorg. Chem. 38, 5964–5977]. There is a crystallographic mirror plane containing the Hf atom, one chloride ligand and the central diketiminate C atom. The HfIV ion has slightly distorted square-pyramidal geometry surrounded by two N atoms from the β-diketiminate ligand and by three Cl anions. Coordination bond lengths are Hf—N = 2.181 (3) Å, and Hf—Cl = 2.3148 (15) and 2.3727 (12) Å.

Comment top

Recently, both main element and transition metal complexes with bulky β-diketiminates as a supporting ligand have attracted considerable attention to small molecule activation (Bourget-Merle et al., 2002). Especially, in the group 4, metal complexes of β-diketiminate were sometimes reported as pro-catalysts for the polymerization of olefins (Bourget-Merle et al., 2002), nevertheless only one example of hafnium complex with a bulky β-diketiminate is known, to our best knowledge (Hamaki et al., 2006). In this paper, we report a novel Hf(IV) complex with β-diketiminate, HC[C(Me)N(iPr2C6H3)]2HfCl3. The central Hf(IV) ion has slightly distorted square-pyramidal geometry surrounded by two N atoms from β-diketiminate ligand and by three Cl- anions. The selected geometric parameters are Hf—Cl2 = 2.3148 (15), Hf—Cl3 = 2.3727 (12), and Hf—N4 = 2.181 (3) Å. The reported complex is isomorphous to analogous complexes based on Titanium (Nikiforov et al., 2007) and Zirconium (Kakaliou et al., 1999).

Experimental top

A solution of crude HC[C(Me)N(iPr2C6H3)]2Li(Et2O) (2.0 g, 4.01 mmol, Stender et al., 2001) in toluene (20 ml) was slowly added to HfCl4 (1.28 g, 4.01 mmol) and stirred overnight at room temperature. The solution was filtered through celite and the filtrate was concentrated under reduced pressure to afford a yellow solid. The yellow solid was extracted with n-pentane (20 ml) and cooled to -40 °C to yield yellow single crystals (1.52 g, 2.16 mmol, 54% yield).

Refinement top

All H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.95 (aromatic CH), 0.98 (methyl CH3) or 1.00 Å (methine CH), and Uiso(H) = 1.2 Ueq(carrier C).
