A silacyclohexane compound of the following formula (I)
wherein R represents an organic residue; at least one of
represents a substituted or unsubstituted trans-1-sila-1,4-cyclohexylene group or trans-4-sila-1,4-cyclohexylene group and the other represents a trans-1,4-cyclohexylene group, L₁ and L₂ independently represents H, F, Cl or CH₃; X represents an organic residue or CN, F, Cl; and m and n are, respectively, 0 or 1 provided that m + n = 1. Silacyclohexane compounds are useful in liquid crystal compositions and also in liquid crystal devices.
