Organosiloxane groups have been used as components of metal-containingliquidcrystals (metallomesogens). It has been found that the disiloxane unit aids mesophase formation, stabilising an enantiotropic smectic A phase over a wide temperature range. The overall effect of an organodisiloxane unit is to lower the melting point relative to an alkyl substituted complex while increasing the clearing temperature
