N2 - Glasses in the quasi-binary system (As4S6)x(P4S10)1-x x = 0.1, ..., 1.0, are produced and studied by thermal analysis, X-ray, and Raman spectroscopy. The phase diagram of the system and the critical cooling rate for glass formation both have their maximum at x = 0.5, corresponding to the compound As2P2S8; the X-ray structure of recrystallized samples can be described as a sum of the As2P2S8 (x = 0.5)- and the P4S10-structure (As4S6 not visible); Raman spectra of the glasses are again sums of As2P2S8- and As4S6/P4S10-spectra. All these observations support the assumption that a stable building block corresponding to the 1:1 compound As2P2S8 and surplus As4S6 (or P410) are the essential elements of the structure in the glasses.
