In the title methyl-ene-bridged di(tetra-hydro-pyrimidinium) salt, C33H50N4 (2+)·2Br(-)·C2H5OH·H2O, the two tetra-hydro-pyrimidinium rings have envelope conformations with the central CH2 C atom as the flap. Their mean planes are inclined to one another by 73.31 (13)° and the attached benzene rings are inclined to one another by 67.39 (15)°. The methylene-C-N bond lengths in the tetra-hydro-pyrimidinium rings are 1.314 (3) and 1.304 (3) Å, values typical for C=N double bonds. The distances betwe ...[more]
