The orthorhombic crystal structures of shattuckite, Cu5( SiO3)4(OH)2 and planchétite, Cu8(Si4011)2(OH)4 H2O, have been solved. Shattuckite contains silicate chains similar to pyroxene in a complex association with copper atoms, while the closely related planchéite contains silicate chains similar to amphibole.
