(Z)-2,3-Bis(4'-[2.2.2]paracyclophanyl)but-2-ene and μ-η6:η6-[(Z)-2,3-Bis(4'-[2.2.2]paracyclophanyl)but-2-ene]-bis[(hexafluoroantimonato-F)silver(I)] Toluene Dichloromethane (1/1/1)

The free ligand, C₅₂H₅₂, displays approximate twofold symmetry, with a C=C bond of 1.337 (4) Å and an essentially planar olefin geometry. The (methyl C)–(olefin C)–(cyclophane C) angles are narrow [113.0 (2)°]. In the disilver(I) complex, [Ag₂(SbF₆)₂(C₅₂H₅₂)].C₇H₈.CH₂Cl₂, the olefin geometry is not greatly changed. The Ag—C distances vary from 2.498 to 2.696 (5) Å and there is a short Ag—F contact of 2.545 (4) Å. The dichloromethane molecule occupies the cleft between the primary aromatic rings.
