Difference electron density maps revealed the presence of disordered 
BF4-, lattice solvate water molecules, which were ultimately modeled 
through the use of the SQUEEZE subroutine of the PLATON software suite. 
PLATON Reference: P. v.d. Sluis & A.L. Spek. Acta Cryst. (1990), A46, 194. 
Three larger voids and three small voids per lattice were found. 
The larger and the smaller void comprises total 
volumes of about 480 and 170 A3, respectively, and contributes total 
of 181 and 60 electrons, separately. Each larger void was thus assigned 
to 4 disordered BF4- and 2 water molecules, which contribute 
4x41+2x10 = 184 electrons, and occupy about 440 A3 in space. 
Each smaller void was thus assigned to 6 water molecules, which contribute 
6x10 = 60 electrons, and occupy about 120 A3 in space. The larger volume of 
the void may be a result of the disorder. The contributions have been 
included in all derived crystal quantities although the precise composition 
of the lattice solvate is somewhat speculative.
