Abstract
The crystal structures of two salt crystals of 2,2-bis-(4-methyl-phen-yl)hexa-fluoro-propane (Bmphfp) with amines, namely, dipyridinium 4,4'-(1,1,1,3,3,3-hexa-fluoro-propane-2,2-di-yl)dibenzoate 4,4'-(1,1,1,3,3,3-hexa-fluoro-propane-2,2-di-yl)di-benzoic acid, 2C5H6N+·C17H8F6O4 2-·C17H10F6O4, (1), and a monohydrated ethyl-enedi-ammonium salt ethane-1,2-diaminium 4,4'-(1,1,1,3,3,3-hexa-fluoro-propane-2,2-di-yl)dibenzoate monohydrate, C2H10N2 2+·C17H8F6O4 2-·H2O, (2), are reported. Compounds 1 and 2 crystallize, respectively, in space group P21/c with Z' = 2 and in space group Pbca with Z' = 1. The crystals of compound 1 contain neutral and anionic Bmphfp mol-ecules, and form a one-dimensional hydrogen-bonded chain motif. The crystals of compound 2 contain anionic Bmphfp mol-ecules, which form a complex three-dimensional hydrogen-bonded network with the ethyl-enedi-amine and water mol-ecules.
