Crystal growth, crystal structure and pyroelectric properties of the polar hexagonal antimony tartrates M-II[Sb-2(C4H2O6)(2)]center dot 2H(2)O (M-II = Ca, Sr, Pb)
Single crystal growth of lead antimony tartrate dihydrate, Pb[Sb-2((+)C4H2O6)(2)]2H(2)O, was successfully performed. The determined polar hexagonal crystal structure is isomorphous to the corresponding calcium and strontium antimony tartrates dihydrates. New results of crystal growth and the redetermination of the crystal structures of the nonlinear optical crystal Sr[Sb-2((+)C4H2O6)(2)]2H(2)O and its calcium analogue are reported, together with investigations of the thermal stability and the pyroelectric properties of these polar crystals
