M. Coutanceau et al., PREPARATION AND CHARACTERIZATION OF A NEW STRONTIUM THALLIUM OXIDE - SR2TL2O5, Comptes rendus de l'Academie des sciences. Serie II. Mecanique, physique, chimie, astronomie, 320(10), 1995, pp. 531-537
A new strontium thallate has been prepared by direct solid state inter
action of SrO with Tl2O3 at 900-degrees-C. Its composition, Sr2Tl2O5,
was determined using physical and chemical analyses. TEM studies and X
RD analysis show that the crystal symmetry is orthorhombic with unit c
ell parameters: a = 3.502(2) angstrom; b = 11.506(9) angstrom; c = 13.
798(9) angstrom; possible space groups are C m c2(1), C c2m, C m cm.
