Crystal Lattice Structures Web Site
A really nice site with several lattice structures indexed by several methods, and new structures are continuously being added. I find it useful for getting images for problems sets and exams.

This paper from Chemistry: A European Journal by Manolis Manos and Mercouri Kanatzidis (link provided below in Web Resources) describes the ion-exchange chemistry of a layered sulfide (KMS-1) that exhibits an enhanced preference for soft metal cations (Cd2+, Pb2+, and Hg2+) replacing K+ in between the metal sulfide layers of KMS-1. Not only does this paper provide a practical application of hard-soft acid-base theory (HSAB), but it provides an accessible introduction to the technical literature for undergraduates, par
I designed this lab experiment to introduce students to the uses of powder X-ray diffraction in the context of the synthesis of a technologically relevant material. Zinc oxide nanoparticles can be synthesized readily with reagents that are inexpensive and relatively benign with regard to student use and waste disposal. Two experiments described in J. Chem.
This paper, while not fundamentally groundbreaking, serves as a nice introduction to the field of mesoporous materials. I like that it covers synthesis, characterization, and an application of the materials. I have used this paper in our senior seminar course as the basis for discussion of this area of chemistry. Discussion questions cover aspects of sol-gel chemistry, powder diffraction, gas adsorption, IR, solid state NMR, UV-Vis, and catalysis.

JMol site http://firstyear.chem.usyd.edu.au/calculators/solid_state.shtml how common inorganic structures are built from the filling of interstitial sites in CCP and HCP lattices.
The site is used as post-work for a hands-on lab about packing (http://firstyear.chem.usyd.edu.au/LabManual/E12.pdf).
The Interdisciplinary Education Group at the University of Wisconsin Madison Materials Research Science and Engineering Center (MRSEC) has a fabulous website with a wide variety of great resources for teaching about materials and the nanoworld at all levels. A favorite "corner" of this website that I refer to a lot in my own teaching is the library of so-called Resource Slides on a variety of topics. These Resource Slides are divided up into 36 topical Slide Shows and include wonderful graphics to use in class presentations. Slide Shows include:
