1,4-Bis(4'-[2.2.2]paracyclophanyl)buta-1,3-diyne and its Bis[silver(I) hexafluoroantimonate] Complex
The free ligand, C52H46, crystallizes with imposed twofold symmetry and its disilver(I) complex, μ-η6:η6-[1,4-bis(4′-[2.2.2]paracyclophanyl)buta-1,3- diyne]-bis[(hexafluoroantimonato-F)silver(I)] bis(dichloromethane) solvate, [Ag2(SbF6)2(C52H46)].2CH2Cl2, with inversion symmetry. The planes of the arenes directly bound to the diyne spacer subtend an interplanar angle of 26° in the free ligand, whereas they are exactly coplanar in the complex. The spacer is linear, with a C4C4i lengths of 6.65 and 6.74 Å in the free ligand and the complex, respectively. The complex crystallizes with one molecule of dichloromethane per asymmetric unit. A short AgF contact of 2.636 (8) Å is observed.
