Abstract
Scolecite, CaAl2Si3O10 · 3 H2O, monoclinic (space group Cc), but described here in the pseudo-orthorhombic setting of Fd, with a = 18.508(5), b = 18.981(5), c = 6.527(2) Å, β = 90.64(1)° in analogy to natrolite. 225 parameters, including hydrogen atoms, were refined anisotropically from 1319 neutron diffraction reflections, the final conventional R value being 2.0%. Tetrahedral Si4+ and Al3+ are well-ordered as well as the three water molecules. Hydrogen bonding is discussed.Keywords
