Abstract
Lead(II) complex with thenoyltrifluoroacetone has been prepared and characterized by IR spectroscopy, powder and single crystal X-ray diffraction. Crystal data for PbO4S2F6C16H8: a = 20.457(4) Å, b = 11.292(2) Å, c = 8.409(2) Å; β = 91.37(3)°, space group C2/c, Z = 4, d calc = 2.222 g/cm3. The molecule of the complex is non-planar, average distances Pb-O are 2.384 Å, chelate angle O-Pb-O is 75.0°. The structure is of polymeric chain nature, Pb...Pb separation in the chains being 4.311 Å. The complex Pb(ttf)2 is stable under heating up to 250°C. The compound is less volatile than Cu(ttf)2 or Fe(ttf)3.
