New covalently bonded “macro-tetrahedral compounds" were synthesized under high-pressure condition and the atom insertion was attempted to promote functionality. Ternary thio-borates, CaB_2S_4 and Li_2B_2S_5, were successfully synthesized at 3-5 GPa and600-1000℃ and their crystal structures were analyzed. Photo-luminescence was observed in Eu-doped CaB_2S_4 when excited at 340-460 nm. Structural analysis of Li_2B_2S_5 strongly suggests that this phase is a candidate material for low-temperature Li-ion conductor.
