Sažetak
Structural interpretation of Raman and IR spectra, and X-ray diffraction study give evidence to the fact that the adding of mercury into binary glass-forming system causes the formation of α-HgS and β-As4S4 at CHg > 2 at.%. Slow quenching of the melt of HgAsS2 compound results in the separation of α-HgS and β-As4S4. In the chain-like model of a-As2S3 structure, the addition of Hg atoms results in the increase of chain dimensions from 1.42 to 1.8 nm.
