摘要
The crystal and molecular structure of Sc(CH3COCHCOCF3)(3) has been determined by X-ray diffraction. The compound crystallizes as pure mer-isomer in the orthorhombic space group Pbca with lattice parameters a=15.166(8) angstrom, b=13.560(7) angstrom, c=19.327(10) angstrom, alpha=beta=gamma=90 degrees, V=3974(4) angstrom(3), Z=8. The complex at 100 K is partially disordered in the crystal structure in an approximate 5:1 ratio with 83% fluorine population at C-11 and 17% at C-15. NMR data is compared to that previously reported.
