Abstract

Mercury thioarsenate glasses (HgS)x(As2S3)1−x, 0.0 ≤<italic>x</italic>≤ 0.5, form a hybrid (HgS2/2)nchain/AsS3/2pyramidal network, highly unusual for metal chalcogenide glasses. This network is evidenced by Raman spectroscopy and DFT modelling and consistent with thermal properties. Nevertheless we cannot exclude completely the presence of a small fraction of HgS4/4tetrahedral units.
