... sites are linked, by hydrogen-bonding to Cl sites, which sit on the triad axis. Each lattice has one Cl above and one below the Ca-Cu polyhedral plane. Consequently, the layers are stacked, along 〈001〉, with two Cl sites between layers. In addition to this kapellasite-like topology, an extra c /2 site...

...W. Krause; H.-J. Bernhardt; R. S. W. Braithwaite; U. Kolitsch; R. Pritchard Abstract Kapellasite, Cu 3 Zn(OH) 6 Cl 2 , is a new secondary mineral from the Sounion No. 19 mine, Kamariza, Lavrion, Greece. It is a polymorph of herbertsmithite. Kapellasite forms crusts and small aggregates up to 0.5 mm...
