Other compounds with this structure
LiNiPO$_{4}$
- This is a high pressure phase. At some point below the experimental pressure of 6.5GPa it transforms into the ground state, $\beta$–LiMPO$_{4}$, which has the monticellite (CaMgSiO$_{4}$) structure.
- This is a the quaternary form of Na$_{2}$CrO$_{4}$ ($H1_{8}$).
