Overview of molecular packing in the cocrystal (tftib)(PPh3). a Each of the iodine atoms of the per tftib molecule is involved in a short I···P interaction with a neighboring PPh3 unit, an I···π contact with another neighboring PPh3 molecule or a short I···F contact to a neighboring tftib molecule. b Pairs of tftib molecules in the crystal structure stack with phenyl rings of two neighboring PPh3 moieties. The cocrystal structures of (tftib)(AsPh3) and (tftib)(SbPh3) are isostructural and corresponding crystal structure views are shown in the Supplementary Fig. 1
