Abstract

Abstract : Two new inorganic metal borate derivatives, Sr5 TeO2 (BO3 )4 and NaSr5 (BO3 )(SiO4 )2, have been obtained through a high temperature solid reaction method. Abstract : Two new inorganic metal borate derivatives, Sr5 TeO2 (BO3 )4 and NaSr5 (BO3 )(SiO4 )2, have been obtained through a high temperature solid reaction method. Sr5 TeO2 (BO3 )4 crystallizes in a tetragonal space group of P 4/ mnc featuring a three-dimensional (3D) structure composed of a porous 3D strontium framework stabilized by the unique zero-dimensional (0D) [TeO2 (BO3 )4 ] 10− anions. NaSr5 (BO3 )(SiO4 )2 crystallizes in a monoclinic space group of P 21 / c with a 3D structure consisting of a splendid strontium 3D framework strengthened by isolated BO3 and SiO4 groups. The sodium cations located in the empty space of the structure. Thermal stability analyses, optical property measurements and theoretical studies of the compounds were performed. Refractive index calculations revealed that the birefringence of Sr5 TeO2 (BO3 )4 and NaSr5 (BO3 )(SiO4 )2 is 0.048 and 0.029, respectively, at 1064 nm.
