Cu4P4X4Fe2 (X = Cl, Br) cages are formed upon reactions of octaethyl-1,1'-diphosphaferrocene (odpf) with the respective Cu-1 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-1 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-1 ions show a slight pyramidalization at the metal atom and somewhat short contacts to the other tricoordinate Cu-1 ion in 2 or the Cu-3-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-1 ions.
