Аннотация: New ternary molybdate Cs2NaBi(MoO4)(3) is synthesized in the system Na2MoO4-Cs2MoO4-Bi-2(MoO4)(3). The structure of Cs2NaBi(MoO4)(3) of a new type is determined in noncentrosymmetric space group R3c, a=10.6435(2), c=40.9524(7) angstrom, V=4017.71(13) angstrom(3), Z=12 in anisotropic approximation for all atoms taking into account rПоказать полностьюacemic twinning. The structure is completely ordered, Mo atoms are tetrahedrally coordinated, Bi(1) and Bi(2) atoms are in octahedra, and Na(1) and Na(2) atoms have a distorted trigonal prismatic coordination. The Cs(1) and Cs(2) atoms are in the framework cavities with coordination numbers 12 and 10, respectively. No phase transitions were found in Cs2NaBi(MoO4)(3) up to the melting point at 826 K. The compound shows an SHG signal, I-2w/I-2w(SiO2)=5 estimated by the powder method. The vibrational properties are evaluated by Raman spectroscopy, and 26 narrow lines are measured.
