The synthesis and crystal structures of guanidinium monofluorophosphate and hydrogen monofluorophosphates with the following cations: piperazinium, di‐ and triethylammonium, guanidinium, and dimethyluronium, are described and discussed. The structures of the acid salts consist of hydrogen‐bonded HPO 3 F tetrahedra, which form infinite chains or cyclic dimers. The organic cations link these units together. All of the hydrogen bond systems observed consist of short O—H···O and longer N—H···O bonds. No O—H···F or N—H···F bonds were found. The F atom avoids hydrogen acceptor positions in the structures. The thermal behavior of [NHEt 3 ]HPO 3 F was also studied.
