  • This structure is the enantiomorph of the ThBC (ABC_tP24_91_d_d_d) structure, and was generated by reflecting the coordinates of the space group #91 structure through the $z=0$ plane.

Simple Tetragonal primitive vectors:

\[ \begin{array}{ccc} \mathbf{a}_1 & = & a \, \mathbf{\hat{x}} \\ \mathbf{a}_2 & = & a \, \mathbf{\hat{y}} \\ \mathbf{a}_3 & = & c \, \mathbf{\hat{z}} \\ \end{array} \]
