Abstract

The crystal structures of 12 argyrodite type copper compounds with the general formula Cu((12-n))B(n+)Q(6-y)(2-)X(y)(-) (B = P, As, Si, Ge; Q = S, Se; X = Cl, Br, I) were refined. The positions of the copper atoms were refined by using a non-harmonic approach. All polymorphic argyrodites were investigated in their cubic high temperature modification crystallizing in spacegroup F (4) over bar 3m ...
