NaCl has a face centered cubic unit cell structure. It is made up of 4 Na+ cations and 4 Cl- anions that occupy sites in a central position, as well as faces, edges and corners. Note that the price is for the entire model which consists of 125 atoms. The unit cell has just 27 atoms.
A FCC unit cell can also be seen this in the spacefilling version shown in the Unit style model this ball & spoke NaCl unit cell model.
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years and are compatible with every molecular model kit we have sold. This level of quality may appear expensive but no parts support from other vendors costs even more.
