We have studied the formation of crystalline and glassy alloys in the Ag3GeS3Br-GeS2 system (0–52 mol % GeS2; Ag3GeS3Br is a glass-forming phase of variable composition) and determined the crystallographic parameters of the Ag3.179(9)Ge1.474(5)S4Br alloy as the saturated solid solution of GeS2 in Ag3GeS3Br: sp. gr. P213, a = 10.16572(3) Å, Z = 4. The electrical conductivity of the crystalline and glassy alloys was measured in the temperature range 250–410 K by a dc probe technique. The current carriers in the alloys are silver cations and halogen anions. We obtained materials with superionic conductivity and proposed a model for conduction in the alloys.
