In calcium fluoride crystals, each Ca2+ion is surrounded by 8 F-ions, forming a cubic densely packed structure with a coordination number of 8; And each F - ion is surrounded by four Ca2+ions with a coordination number of 4. Therefore, the coordination number of calcium fluoride crystals is Ca2+ion 8 coordination and F-ion 4 coordination. This coordination relationship is determined by the face centered cubic structure of calcium fluoride crystals, where Ca2+ions are located at the nodes of the face centered cubic structure, while F - ions are filled in the octahedral voids.
The above is an answer to how the coordination number of calcium fluoride crystals is formed. We hope it is helpful to you. If you have any questions, please feel free to consult online or leave a message.
