Molecular Structure of Mesitylammonium Tetrafluoroborate

Abstract

The title compound, MesNH3+BF4-·(CH3CN) (1) (Mes = 2,4,6-trimethylphenyl), crystallizes in the triclinic space group P1 with a = 8.5468(4), b = 12.9136(7), c = 13.2661(7)A, α = 64.303(3)°, β = 74.452(2)°, γ = 73.177(2)°, V = 1245.54(11)A3, Z = 2. The crystal packing is stabilized by strong interionic N-H…F and N-H…N hydrogen bonds between anions and cations, resulting in a three-dimensional network structure. One of the two tetrafluoroborate anions is disordered [site occupation factors 0.811(2) and 0.189(2)].
