摘要：
Synthesis and X-ray structural investigation of hafnium(IV) pivalyltrifluoroacetonate were carried out. Crystallographic data for C32H40F12HfO8 are: a = 19.913(3) angstrom, b = 11.8764(18) angstrom, c = 16.530(3) angstrom; beta = 95.538(2)degrees; space group Cc, Z= 4, d(calc) = 1.637 g/cm(3), R = 0.035. The structure is molecular; it is composed of discrete mononuclear Hf(ptac)(4) molecules connected with each other by van der Waals interactions. The hafnium atom coordinates eight oxygen atoms belonging to four beta-diketonate ligands; Hf-O distances are within the range 2.133-2.199 angstrom.
