In the title compound, C18H46N2OSi22+.2ClO(4)(-), the cations lie in s
pecial positions on the crystallographic twofold axis. The contacts be
tween N+ and ClO4- build up a three-dimensional net. The Si-O-Si angle
is relatively small [between 141.8(3) and 144.4(5)degrees] and depend
s on the measuring temperature.
