摘要: A series sulfides of A–Ag–S (1–3; = K, Rb, Cs), Na5AgGe2S7 (4), and Rb2Ag2GeS4 (5) have been prepared solvothermally in the presence excess sulfur. Among these compounds, 4 is a new compound that has novel layered structure; others were obtained under mild conditions. The results showed sulfur could increase solubility silver sulfide lower synthetic temperature effectively. mineralizer effect discussed detail.
