- (Günzel, 1958) place this structure in space group $P\overline{3}$ #147 but (Cenzual, 1991) showed that all the atoms have $z$ coordinates which are are either 1/4 or 3/4. In that case there is a six-fold rotation axis, making the space group $P6_3/m$ #176.
- (Cenzual, 1991) also note that (Günzel, 1958) list the $z$ coordinate of the (3d) copper atoms as 1/4, but as seen from the figures it must be 3/4 in their paper, and 1/4 here.
\[ \begin{array}{ccc}
\mathbf{a_{1}}&=&\frac{1}{2}a \,\mathbf{\hat{x}}- \frac{\sqrt{3}}{2}a \,\mathbf{\hat{y}}\\\mathbf{a_{2}}&=&\frac{1}{2}a \,\mathbf{\hat{x}}+\frac{\sqrt{3}}{2}a \,\mathbf{\hat{y}}\\\mathbf{a_{3}}&=&c \,\mathbf{\hat{z}}
