CrystalMaker Crystal Structures Libraries
This folder contains the CrystalMaker structural libraries.
These libraries now contain
some 600 structures, including nearly 300 minerals (e.g., all
the major rock-formingminerals) plus many other important phases.
All of the structures files are saved in
CrystalMaker binary format: ready for immediate display in
CrystalMaker versions 7-
8 for Mac, or versions 1-2 for Windows.
You can use CrystalDiffract to simulate powder diffraction
patterns for the crystalstructures (version 5 for Mac or version 1
for Windows). SingleCrystal (Mac or
Windows) can be used to simulate single-crystal diffraction
patterns, includingtransmission electron microscope diffraction
patterns, reciprocal lattice sections - and
even stereographic projections.
For each structure we've taken some time trying to find the
most-informative view
direction and model type; you should also find that in most
cases the Notebookwindow contains valuable information about each
structure - including, wherever
possible, details of the original crystal structure
refinement.
Part I: Type Structures
(a) Lattice Types. This folder contains examples of the 14
Bravais Lattices, plus theRhombohedral Lattice type. This should
prove useful for teaching purposes.
(b) Basic Structure Types. This folder is designed to give a
broad overview of therange of structures adopted by simple
inorganic compounds: metals, and AX,
AX2, ABX3, etc. compounds.
Part II: Reference Library
(c) Minerals Library. The Minerals Library is by far the biggest
library here. Whilstits relevance to geoscientists goes without
saying, it also contains many phases
which may be of interest to other scientists: included under the
"Minerals"banner are important natural zeolites, perovskites and
oxide phases, plus
crystal-chemistry favourites like NaCl (halite), diamond, zinc
sulphide (twopolymorphs), etc.
The Minerals Library is subdivided along chemical grounds - with
the silicate
minerals further subdivided according to the degree of
polymerization of
tetrahedral unit
Thematic Minerals Guide. As something of an appendix, we've
included an
alternative classification: a "Thematic Mineral Guide"
containing highly-selective entries for different themes (e.g., gem
minerals, high-pressure
minerals, ore minerals, etc.)
(d) "Other Inorganics" Library. The second-biggest library is
the "Inorganics" one.
Of course, strictly-speaking, minerals come under the
"inorganics" banner - buthere we've placed the synthetic and other
non-mineralogical phases. Please
remember to double-check the Minerals Library, so as not to miss
importantnaturally-occurring phases!
