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)Å, α = 64.303(3), β = 74.452(2), γ = 73.177(2), V = 1245.54(11)Å3, 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)]. 2008 © The Japan Society for Analytical Chemistry.
