It is found that in contrast to acanthite the possible distances between silver atoms in cubic argentite are too small to allow Ag atoms to occupy metal sublattice sites with a probability of 1 It is shown that the 010 and 001 atomic planes of acanthite are parallel to the 1 1 bar 0 and 221 planes of argentite respectively
