The bis[silver(I) trifluoromethanesulfonate] complex of the fully conjugated tubelike hydrocarbon 5,24:6,11:12,17:18,23-tetra[1,2]benzenotetrabenzo[a,e,i,m]cyclohexadecene crystallizes with two molecules of water and two of toluene, and thus has the formula [Ag2(C56H32)(C7H8)2(H2O)2](CF3SO3)2. The formula unit of the latter displays inversion symmetry, the ligand itself approximate D4h symmetry. Each Ag+ ion is coordinated by one carbon atom of each of two adjacent rings of the ligand, one water oxygen and one toluene C-C bond.
