- Аннотация: The synthesis, crystal structure, and characterization of a few new noncentrosymmetric rare-earth borates of gaudefroyite family Sr2MBi(REEO)3(BO3)4 (M = Ca, Sr, Ba; REE = Y, Eu)are represented.Samples of Sr2MBi(YO)3(BO3)4 (M = Ca, Sr, Ba) borates were synthesized by multi-step solid state reactions.The crystal structures of Sr3Bi(YO)3(BO3)4, Sr2CaBi(YO)3(BO3)4 and Sr2BaBi(YO)3(BO3)4 were refined to R1 0.059, 0.058 and 0.018, respectively. Second-harmonic generation measured with Kurtz–Perry powder technique revealedan increase in the nonlinear optical activity of materials upon partial substitutions of Srfor Ca and Ba in the Sr3Bi(REEO)3(BO3)4 and its decrease if Y atoms are replaced by Eu.Thermal expansion coefficients for Sr2MBi(YO)3(BO3)4 (M = Ca, Sr, Ba) borates and Ca4(MnO)3(BO3)3(CO3) gaudefroyiteare calculated for the first time. Thermal expansion of these compounds is almostisotropic due to thearrangement of BO3 units which are located in the ab and acplanes.
