  Liquid crystalline (LC) organosiloxanes with two terminal cyanobiphenylyl groups at tached to a linear or cyclic siloxane center through an aliphatic spacer (CH2)(n) with n=10 synthesized. The ability of compounds to pass into the LC state was confirmed by thermooptical, X-ray diffraction, and calorimetric measurements. The temperatures and the enthalpies of phase transitions were determined. The types of LC structures and the capability of one compound for polymesomorphism to form the chiral SmC* phase without a chiral center in the mesogenic group were established. The temperatures and the enthalpies of the reversible phase transitions, crystal reversible arrow SmC reversible arrow S(m)A reversible arrow melt and crystal reversible arrow S(m)A reversible arrow melt, for linear and cyclic LC otganosiloxanes, respectively, were determined. Models of molecular packing in the S(m)A and SmC* phases were proposed based on X-ray diffraction data. A specific feature of the S(m)A phases of new LC organosiloxanes is a negative gradient of the temperature dependence of the interlayer spacing.
