Synthesis, characterization and crystal structure of a new mixed alkali and alkaline-earth metal borate Rb9Ba24(BO3)19

Abstract

A new mixed alkali and alkaline-earth metal borate, Rb9Ba24(BO3)19, has been synthesized by high-temperature solution method. Single crystal X-ray crystallographic investigation reveals that it crystallizes in the trigonal space group P"3" @#x0305;m1 (No. 164) with unit cell parameters of a = b = 16.977(3) Å, c = 7.282(2) Å, and Z = 1. Rb9Ba24(BO3)19 possesses intricate three-dimensional (3D) Ba-O framework with three types of infinite channels viewing along the c axis where the Rb+ cations and isolated BO3 units are located. The synthesis, single crystal growth, thermal behavior, IR spectrum and UV-vis-NIR diffuse reflectance spectrum of the title compound have been comprehensively studied.
