    • -, with a complex array of weak interactions. The two sets of ion pairs are disposed similarly with the substituted aromatic rings lying approximately parallel to each other and to the ab face of the cell, inversion related to generate sheets to either side, while the unsubstituted phenyl rings, approximately parallel to each other, and to the ac faces of the cell, lie approximately normal to the ab and bc faces. Interplanar dihedral angles within the asymmetric unit are as follows: 1/1′',2,2′' 77.9(2)°, 7.4(1)°, 85.8(2)°; 1′/2,2′ 84.9(2)°, 24.5(2)°; 2/2′ 80.0(2)°. The central C-S bonds of the anions lie quasi-parallel to c. The unsubstituted phenyl rings and anions, project outward from the ab plane, interdigitated with those from the next array disposed to either side of z =1/2. The central, more positively charged, iodine atoms interact with nearby oxygen atoms from their companion anions (I(11)...O(11), I(21)...(21) 3.028(4), 2.871(3) Å) forming putative ion pairs. However, the pendant/substituent iodine atoms also interact. Thus (I(14)...O(12) (x, y-1, z) 3.088(3), I(24)...0(22) (x, y-1, z) 3.335(3) Å) linking the pairs into strings; interestingly, despite the seeming noncrystallographic symmetry/equivalence of the two sets of 'ion pairs', the latter interaction for the second pair is less clear-cut, albeit still resulting in string formation, the iodine interacting as well with associated fluorines (I(24)...F(21,23), O(22) (x, y-1, z) 3.556(4), 3.746(3), Å). As might be expected, there are also numerous other 'contacts' from diverse atoms to the iodines at longer distances. The substituted phenyl rings are similarly inclined to the ac face, contacting peripherally at typical interplanar spacings. Insofar as intraspecies geometries are concerned, the C-I distances are remarkably similar (av. 2.100(9) Å), the two C-I-C angles both very close to 90°.
