Tenorite (CuO, $B26$) Structure: AB_mC8_15_a_e-001

Picture of Structure; Click for Big Picture
Prototype CuO
AFLOW prototype label AB_mC8_15_a_e-001
Strukturbericht designation $B26$
Mineral name tenorite
ICSD 16025
Pearson symbol mC8
Space group number 15
Space group symbol $C2/c$
AFLOW prototype command aflow --proto=AB_mC8_15_a_e-001
--params=$a, \allowbreak b/a, \allowbreak c/a, \allowbreak \beta, \allowbreak y_{2}$

  • In (Mehl, 2017) we inadvertently used $\beta$ = 120.34° rather than the correct value of 99.54°. We apologize for the error, and correct it here.

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