Kit NamePart #DescriptionPrice US $
CALCIUM FLUORIDE (FLUORITE)
CAF-1Kit Contents:
24 silver 8-peg calcium ion centers
49 blue 4-peg fluoride ion centers
130-1.25" PVC, clear bonds
Assembly instruction booklet

In the fluorite structure, calcium ions lie in an expanded face centered cube, with fluoride ions filling tetrahedral holes between the cation layers. The coordination number is 4 for the anion and eight for the cation.

The model can be used to show these structural arrangements.
$28.00
CESIUM CHLORIDE
CsCl-1Kit Contents:
26 silver 8-peg cesium ion centers
28 green 8-peg chloride ion centers
97-1.25" PVC, clear bonds
Assembly instructions PDF on this website.

The model exemplifies the cesium chloride type of ionic structure.

Cesium and chloride ions both have a coordination number of eight in this crystal, and its unit cell is simple cubic.
$34.00
SODIUM CHLORIDE
SOD-1Kit Contents:
40 silver 6-peg sodium ion centers
40 green 6-peg chloride ion centers
158-1.25" PVC, clear bonds
Assembly instruction PDF on this website.

The kit demonstrates the halite, or rock salt ionic structure.

The unit cell (cubic face centered for both the sodium and chloride ions) is easily observed using this model. The coordination number of 6, for cation and for anion, is also easy to demonstrate.
$34.00
ZINC SULFIDE (SPHALERITE, OR ZINC BLENDE)
ZNS-1Kit Contents:
50 silver 4-peg zinc ion centers
50 yellow 4-peg sulfide ion centers
140-1.25" PVC, clear bonds
Assembly instruction booklet

Zinc sulfide forms two different mineral forms, sphalerite and wurtzite.

With a coordination numbers of 4, 4, the model is also illustrative of an anionic face centered cube with the cations in tetrahedral holes.
$36.00
ZINC SULFIDE (WURTZITE)
ZNS-2Kit Contents:
43 silver 4-peg zinc ion centers
43 yellow 4-peg sulfide ion centers
100-1.25" PVC, clear bonds
Assembly instruction booklet

Zinc sulfide forms two different mineral forms, sphalerite and wurtzite.

Like sphalerite, wurtzite has 4,4-coordination. Our wurtzite model makes the hexagonal, close packing arrangement easy to observe.
