Brookite Crystal Structure Unit Cell
SKU: 68763W
Build a brookite TiO2 unit cell with the Indigo® 68763W molecular model kit to demonstrate D2h point group symmetry, orthorhombic crystal structure, and the most structurally complex of the three TiO2 polymorphs. Ideal for solid state chemistry, crystallography, photocatalysis, and materials science courses.
The Indigo® 68763W model kit can build a brookite unit cell, the most structurally complex polymorph of titanium dioxide (TiO2). Brookite belongs to the D2h point group and crystallographic space group Pbca. Its orthorhombic symmetry has eight TiO2 formula units per unit cell (Z=8). Each Ti4+ ion is octahedrally coordinated by six O2- ions, but the TiO6 octahedra in brookite share both edges and corners in a distinctive pattern that produces the orthorhombic unit cell. Brookite has a very high refractive index of 2.5, more than diamond's 2.42, and is of interest in optical applications.
Indigo Instruments has held inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (See Skeletal (Orbit/Minit)) that are compatible with every molecular model we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.
