摘要：

Zirconium complex with trifluoroacetylacetone (Tfac) of the composition Zr (Tfac)(4) (I) was synthesized and its structure was determined by X-ray diffraction. In the presence of polymethylaluminoxane, complex I is an active catalyst in ethylene polymerization to linear unbranched polyethylene. Crystals I are triclinic: a = 8.1600(16), b = 11.498(2), c = 15.766(3) angstrom, alpha = 99.20(3)degrees, beta = 103.07(3)degrees, gamma = 107.94(3)degrees, space group P (1) over bar, Z = 2, rho(calcd.) = 1.759 g/cm(3), R = 0.0679. The structure consists of individual mononuclear Zr (Tfac)(4) complexes. The Zr atom coordinates eight O atoms of four beta-diketonate ligands (Zr-O 2.17-2.20 angstrom). The complexes in a crystal are bonded by van der Waals interactions.
