The Ca2Pb(C2H5CO2)6
organic crystals of good optical quality were obtained by a slow evaporation
method. The temperature dependencies of refractive indexes and piezooptical
coefficients were investigated at the region of ferroelectrical phase transition.
The coefficients of the quadratic electrooptical as well as piezo-electrooptical
effect induced by spontaneous polarization were calculated. The obtained
results are discussed on the base of the optical indicatrix equation.
