摘要

The tetragonal polar barium antimony tartrate trihydrate, Ba[Sb-2((+)C4H2O6)(2)]center dot 3H(2)O, was grown to large single crystals of optical quality and several cm dimensions. A vibrational spectroscopy study, thermal expansion measurements and a determination of the pyroelectric properties were performed and possibilities for phase matching for second harmonic generation (SHG) were analysed. The crystals show a remarkable high pyroelectric coefficient, a moderate anisotropy of thermal expansion and allow for type I and type II phase matching for collinear SHG. A redetermination of the crystal structure of Ba[Sb-2((+)C4H2O6)(2)]center dot 3H(2)O at 150 K is given in addition, together with the vibrational spectra and crystal structures of two new related compounds, Ba [As-2((+)C4H2O6)(2)]center dot 3H(2)O and Ba[Sb-2((+)C4H2O6)(2)]center dot 4H(2)O, determined at the same temperature.
