First examples of diprotonated guanazolinium salts with fluoro-anions

A mixed-valence copper chloride coordination polymer composed of one-dimensional cationic and anionic substructures

“…The structure of the H 2 datrz cation in 2 is quite similar to those in known di-protonated triazole salts containing fluoride anions. 39 Guennoun et al reported that increasing protonation leads to the elongation of endocyclic C-N bond lengths and the shortening of exocyclic C-N bond distances. 40 As shown in Table 1, the four endocyclic C-N bond lengths are slightly elongated, while the two exocyclic C-N bonds have slightly shortened C1-N4 (1.306 Å) and C2-N5 (1.308 Å) bond lengths.…”
