GUIDE to Bond insertion

Note

This set is designed to permit assembly of nearly all the fundamental crystal structures in the field of inorganic chemistry and crystallography.
By using this set, fundamental structures of metals such as face-centered cubic Iattice, body-centered cubic lattice, and hexagonal close-packing, and the unit Iattice structures of typical ionic crystals such as rook salt, cesium chloride, zincblende, wurtzite, fluorite, calcite, graphite and spinel can be constructed side by side.
This set is indispensable for research and lectures concerning the formation process of inorganic giant molecules, the form of spaces in a crystal, formation of optical isomers based upon the difference in configuration, determination of unit lattice, and so on.

- Note
Type E set is designed to make 1

= 2.5cm in zinc-blend crystals. The magnification of bond distances of some of the other crystals is an approximate one.
Consequently, bond distances shown in parentheses are not always the same as the bond distances in the crystals themselves, but are those in the models.
