Abstract

The title adduct, [K(C30H24F12I 3NO6)]I, gives an extended tape of cations linked through I⋯I- halogen bonds (XBs), two of them being quite short and one quite long. In the structure, the cation is hosted in a cavity formed by the arms of the podand which presents a closed conformation wherein two tetrafluoroiodobenzene rings are near parallel [dihedral angle = 15.8 (4)°; centroid-centroid distance = 3.908 (5) Å] and the third ring is closer to orthogonal [dihedral angles = 66.28 (14) and 75.20 (19)°] to the other two rings. The coordination sphere of the K+ cation is composed of the six O atoms, the N atom and an F atom in the ortho position of one of the rings.
