About Argyrodite Group
Formula:
Am+(12-n-y)/mDn+X2-6-yZ-y
A = Ag+, Cu+, Cd2+, etc · D = Ga3+, Si4+, Ge4+, Sn4+, P5+, etc · X = S, Se, Te
Z = Cl, Br, I
Z = Cl, Br, I
Many synthetic members are known and have been studied due to their interesting thermoelectric properties.
Compare also spryite, which has both As3+ and As5+ structurally essential.
