Abstract
Synthesis and single crystal X-ray diffraction study were carried out for copper(II) 2,2,6,6-tetramethyl-4-fluoroheptane-3,5-dionate (Bruker AXS P4 automated diffractometer, MoK α radiation). Crystal data for C22H36CuF2O4: a = 5.9165(4) A, b = 10.2787(7) A, c = 10.5223(8) A, α = 81.383(3)°, β = 76.106(3)°, γ = 83.778(3)°, space group P $$\bar 1$$ , V = 612.42(7) A3, Z = 1, d x = 1.264 g/cm3. The structure is molecular; the copper atom has a square plane coordination formed by the oxygen atoms of two β-diketonate ligands; the average Cu-O distance is 1.895 A, ∠O-Cu-O 92.5°. Only van der Waals interactions are realized between the molecules in the structure. The temperature dependences of the saturated vapor pressure were studied by the mass transfer technique, and the standard thermodynamic parameters of sublimation were derived for the complex, ΔH subl 0 = 115.6 ± 1.1 kJ/mol, ΔS subl 0 = 204.9 ± 2.5 J/mol·K.
