Perovskite's unit cell structure is cubic with titanium atoms at the corners, oxygen atoms at the midpoints of the edges with a calcium atom in the center. Its ABX3 cubic crystal structure corresponds to A (Calcium) which is a large, positively charged cation at the centre; B (Titanium), also cations, at the corners with smaller atom X (Oxygen), a negatively charge anion occupying the faces of the cube.
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) atoms & bonds for over 30 years. These parts are compatible with every molecular model kit we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.

There are no printed instructions for assembling this model. However, if you read these specifications & look closely at the completed model & the smaller cube, it should be straightforward.
