RESOURCES ON THE INTERNET

Crystal Lattices by R.B. Young & M. Mehl, U.S. Naval Research Laboratory

Crystal Lattices are shown classified by Strukturbericht Designation, by Pearson Symbol or by Space Group or in classes such as simple cubic, ccp or related, hcp or related, perovskites, etc... Pictures, representations and vector descriptions are collected here for a wide range of structures. xyz coordinates may be downloaded to view the structure in e.g. RasMol

3D Crystal Lattice Images by Prof. S.F. Watkins, Louisiana State University, Baton Rouge

This page shows stereoviews of some lattices and also interstitial holes. Clinographic perspective views of 3D solid structures are necessarily in 2-dimensions! Observing the two stereoview pictures in the correct way gives an apparent 3-dimensional quality to the image, enhancing the ability to visualize it. There's a certain knack to seeing the 3D image at the centre of the field of view - and don't get cross-eyed by staring too long!

Simple Structures by Prof. Winston Chan, University of Iowa

Prof. Chan has written Java applets to allow you to view and manipulate crystal structures within your web browser. These are less versatile than viewing in the CrystalMaker program, but have the distinct advantage of being computer-platform independent - so a good complement to this site if you are using a PC.

Crystal Structures by Prof. Andrew Maverick, Louisiana State University, Baton Rouge

Get the Chime pluggin for your browser and Prof. Maverick has some nice Chime files so that you can view some simple inorganic solids in Ball & Stick or Space-Filling Modes or display various aspects of the arrangement of atoms, all whilst reorienting the structure within your browser.

Crystal Lattice Structures by Barbara & Frederick Sauls, King's College, Pennsylvania

 An introduction to the structures of solids at a simpler level than this course, with two parallel sites, one containing VRML models of the structures, the other using avi movies to show structural features.

3D-Crystals by Alan and Marcus Hewat, Institute Laue Langevin, Grenoble

A demonstration of aspects of structure in a wide range of Inorganic materials and a useful source of 3D crystal structures in VRML, including generation of VRML files for solids from a variety of standard crystallographic formats using the program "xtal-3d".

La Chimie par le Web by Prof. Charles Jacoboni, Université du Maine, Le Mans

Want to read these lectures in French? This comprehensive site offers amongst other attractions the possibility to read the "Structures of Simple Solids" course beautifully translated into French by Prof. Charles Jacoboni.

Lecture 1 (French) ... Lecture 2 (French) ... Lecture 3(French) ... Lecture 4 (French)

Anorganische Chemie - Verschiedene Vorlesungen by Prof. Caroline Röhr, Universität Freiburg

For German speakers there are comprehensive lectures on inorganic materials structures by Prof. Caroline Röhr of the University of Freiburg. Even if you don't read German you will appreciate the VRML files for many structure types, including polyhedral representations.

Inorganic Crystal Structure Database (ICSD)

The ICSD of the University of Bonn is the definitive database of Inorganic Crystal Structures that have been determined by means of diffraction experiments. The structural parameters used to define the structures in these lectures were retrieved from the ICSD through the UK access point, the Chemical Database Service (CDS) at the Daresbury Laboratory, CLRC. You can view a selection of structures from the ICSD in the ILL's demonstration.The CDS service also allows access to the CRYSTMET Database of the NRC, Canada and the Cambridge Structural Database (CSD), which respectively provide structures for metals and C-C/C-H bond-containing materials.

Mineralogy Home Page by Dr David Sherman, University of Bristol

A lot of the simple inorganic structures presented in these lectures occur naturally as minerals and this very approachable mineralogy course will broaden your perspective of the importance of learning about basic structural principles

LOCAL RESOURCES

The University Museum, Oxford

The University Museum of the University of Oxford on Parks Road has some fine collections of minerals. The museum is open from 12:00 - 17:00 Mon-Sat and is well worth a visit.

The Inorganic Chemistry Laboratory (ICL), Oxford

The Abbot's Kitchen of the ICL contains a small display relating to the work of Prof. Dorothy Hodgkin, who won a Nobel Prize for her work in the field of crystallography.

The Chemistry IT Centre, Oxford

Both local and on the internet! You'll find useful resources here in all areas of chemistry, including solids, such as:-

March 1997's Molecule of the Month feature on Gemstones, which includes virtual reality VRML structures.
