6-F3–C6H2C(O)NH]P(O)(X)2, is compared to those of the newly determined structures. The Hirshfeld surface method shows that the crystal cohesions of structures [2,3,6-F3–C6H2C(O)NH]P(O)(X)2 are established via H···H, O···H/H···O, C···H/H···C, and F···H/H···F contacts, while for [OH8C4N]3P(O), H···H and O···H/H···O are the dominant contacts.
