- Above 1112$\pm$8$^\circ$C this transforms into the rock salt ($B1$) structure with disordered carbon vacancies. (Rafaja, 1998) Below that temperature the vacancies order on the (4b) sites of space group $P4_{3}32$ as shown here.
- If we set $x_{2} = 3/8$, $y_{3} = 5/8$, $y_{4} = 3/8$, $x_{5} = 1/8$, $y_{5} = 3/8$, $z_{5} = 1/8$, and place carbon atoms on the (4b) (5/8 5/8 5/8) site then this structure becomes a fully ordered rock salt crystal.
- The current structure may also be found in the enantiomorphic space group $P4_{1}32$ #213.
