Title: Crystal structure of the Ca{sub 3}TaGa{sub 3}Si{sub 2}O{sub 14} compound

Abstract

The absolute crystal structure of the Ca{sub 3}TaGa{sub 3}Si{sub 2}O{sub 14} piezoelectric compound is refined using X-ray diffraction analysis. The unit cell parameters and final R factors are as follows: a = 8.112(1) A, c = 4.9862(6) A, space group P321, Z = 1, R = 0.98%, and R{sub w} = 1.42%. It is shown that the configuration of the absolute crystal structure inherited from the seed material determines the positive sense of the optical activity of the crystal under investigation. The structural and acoustical characteristics of the Ca{sub 3}TaGa{sub 3}Si{sub 2}O{sub 14} crystals are compared with those of the La{sub 3}Ga{sub 5}SiO{sub 14} crystals.
