Abstract: | The Ligand (E)-[4,4,4-Trifluoro-1-(trifluoromethyl)-1,3-bis(trimethylsiloxy)-2-butenyl]di-phenylphosphine The tertiary phosphine (E)-Ph2PC(OSiMe3)(CF3)CH = C(OSiMe3)CF3 (L), 1 and the carbonyl Fe2(CO)9 react to give (OC)4FeL, 2. Bis( 1,1,1,5,5,5-hexafluoropentane-2,4-dionato)palladium(II) and 1 furnish the diphenylphosphido group bridged palladium(II) complex 3 crystallizing from chloroform triclinic in the space group P1 with a = 12.600(3), b = 13.298(3), c = 13.975(3) Å, α = 93.27(2), β = 111.67(2), γ = 106.71(2)° The elementary cell contains Z = 2 formular units and two molecules CHCl3 with two independent molecules 3 each showing an inversion centre. The planar [PdP], four membered ring system and the planar chelate units, exhibit a torsional angle of 6.75° |
