Thermochromism: Mercury(II) Iodide When red-orange Mercury(II) Iodide (HgI2) is heated, it undergoes a phase transition at 126oC to a pale yellow form. As the heated sample cools, it gradually returns to the original red-orange color.
Exploring Solid-State Structure and Physical Properties: A Molecular and Crystal Model ExerciseThomas H. Bindel This laboratory allows students to examine relationships among the microscopicmacroscopicsymbolic levels using crystalline mineral samples and corresponding crystal models. The exercise also reinforces Lewis dot structures, VSEPR theory, and the identification of molecular and coordination geometries. Bindel, Thomas H. J. Chem. Educ.2008, 85, 822.

Stuffed Derivatives of Close-Packed StructuresBodie E. Douglas Examines a variety of stuffed silica crystal structures in terms of the close-packing of one set of atoms or ions (P sites) with other atoms or ions in tetrahedral (T) or octahedral (O) sites and filled or partially filled layers in the regular pattern, PTOT.
