.... Algodonite, Cu 6 As, and allargentum, Ag 7 Sb, have only two crystallographic sites, so that the formulae are misleading. Members of the kaolin and serpentine groups have a 1:1 layer structure in contrast to the chlorite family, which has a 2:1:1 layer structure. The formulae of the kaolin- and serpentine...
