  • This is one of a variety of SiO$_{2}$-like aluminum phosphates. We give more detail about all of these structures in the Silica and Aluminum Phosphate tutorial page.
  • The metallic sites in this lattice are randomly occupied by aluminum and phosphorous atoms. We have arbitrarily labeled these as aluminum.
  • Both (Withers, 2005) and the earlier work of (Richardson, 1992) sometimes refer to this structure as being in space group $Cmc2_{1}$, but they present data for an averaged structure in space group $Cmcm$. We use that data here.

\[ \begin{array}{ccc} \mathbf{a_{1}}&=&\frac{1}{2}a \,\mathbf{\hat{x}}- \frac{1}{2}b \,\mathbf{\hat{y}}\\\mathbf{a_{2}}&=&\frac{1}{2}a \,\mathbf{\hat{x}}+\frac{1}{2}b \,\mathbf{\hat{y}}\\\mathbf{a_{3}}&=&c \,\mathbf{\hat{z}} \end{array}\]
