Abstract
New iron(III) complexes with a fluorinated methoxy-substituted β-diketonate L = 1,1,1-trifluoro-5-methoxy-5-methylhexane-2,4-dionate are prepared. Heteroligand complexes with the composition [Fe(OR)L2]2 (R = Et or i-Pr) and the homoligand complex FeL3 are isolated. The crystal structure of these complexes is molecular and is built of binuclear and mononuclear molecules, respectively. Methoxy groups of ligand L are not involved in the coordination. The crystallographic data for fac-FeL3: C24H30F9O9Fe, P21, a = 10.462(2) Å, b = 14.826(3) Å, c = 10.7097(18) Å, β = 114.752(5)°, V = 1508.56 Å3, Z = 2, d = 1.518 g/cm3; for [Fe(OEt)L2]2: C36H50F12O14Fe2, , a = 8.6968(15) Å, b = 10.9946(17) Å, c = 14.019(2) Å, α = 67.435(5)°, β = 82.812(6)°, γ = 80.323(6)°, V = 1217.5(3) Å3, Z = 1, d = 1.427 g/cm3; for [Fe(Oi-Pr)L2]: C38H54F12O14Fe2, Pbca, a = 17.734(1) Å, b = 15.6851(10) Å, c = 17.9767(12) Å, V = 5000.4(5) Å3, Z = 4, d = 1.427 g/cm3. The complexes can be re-sublimated without being decomposed upon heating in a vacuum (~10–2 Torr). [ABSTRACT FROM AUTHOR]
