摘要：

Single crystals of Ba3Na0.32Nb6O12(Si2O7)(2) were grown for the first time. The use of an alkali/alkaline earth eutectic flux facilitated the crystal growth. Ba3Na0.32Nb6O12(Si2O7)(2) , a mixed valent Nb(V)/Nb(IV) compound, crystallizes in the noncentrosymmetric hexagonal space group P-62m with a = 8.9998(10) angstrom and c = 7.8119(17) angstrom. The temperature dependence of the magnetic susceptibility was measured and found to be paramagnetic across the entire 2-300 K temperature range measured. Although noncentrosymmetric, Ba3Na0.32Nb6O12(Si2O7)(2) was not found to be second harmonic generation active. Ba3Na0.32Nb6O12(Si2O7)(2) was further characterized by IR and UV/Vis spectroscopies.
