Zusammenfassung

Cu₄P₄X₄Fe₂ (X = Cl, Br) cages are formed upon reactions of octaethyl-1,1′-diphosphaferrocene (odpf) with the respective Cu^I halide in CH₂Cl₂/CH₃CN solvent mixtures. These cages have adamantoid Cu₄X₄P₂ cores with two planar anelated CuP₂Fe rings as the flaps. Both complexes 1 and 2 feature tri- and tetracoordinate Cu^I ions and an additional acetonitrile solvent molecule in the crystal. In 1, the solvent molecule is coordinated to one copper ion whereas it remains uncoordinated in 2. The tricoordinate Cu^I ions show a slight pyramidalization at the metal atom and somewhat short contacts to the other tricoordinate Cu^I ion in 2 or the Cu₃-triangle in 1. NMR spectroscopy revealed easy decoordination of the acetonitrile ligand from 1 and a dynamic “windshield-wiper”-type process that interconverts the differently coordinated phospholide rings of each odpf ligand and the tri- and tetracoordinate Cu^I ions.
