- 中文摘要: A series of titanium(IV) acetylacetonate (acac) complexes, Ti(acac)Cl3 (THF) (2), [Ti(acac)Cl2(THF)]2 (m-O) (3), [Ti(O-I-Pr)Cl3(acac)]-(HNEt3+) (5), and Ti(O-I-Pr)Cl2 (acac)(THF) (6), were prepared from reactions of TiCl4 or Ti(O-I-Pr)Cl3 with 2,4-pentanedione (Hacac) in CH2Cl2 or THF with or without the presence of NEt3. The x-ray structural analyses were carried out on complexes 2 and 6. Complex 2 crystallizes in the monoclinic P21/n space group with a = 8.664(1) A, b = 11.859(1) A, c = 14.320(1) A, b = 103.94(1)o, R = 0.0571, Rw = 0.0620, and Gof = 1.10. Complex 6 crystallizes also in the monoclinic P21/n space group with a = 9.074(2) A, b = 11.499(2) A, c = 16.549(4) A, b = 101.96(2)o, R = 0.0492, Rw = 0.0671, and Gof = 1.49. Based on the solid state structures of complexes 2 and 6, the relative bonding order of -O-I-Pr > Cl- > acac- > THF is established.
