Stage: 5 Challenge Level:
Try drawing the tetrahedral molecule with some axes on it and use
simple trigonometry to define the coordinates of each of the outer
atoms. It may be useful to let one of the bottom atoms to lie along
an axis. To find the coordinates of the other two bottom atoms, it
is easiest to draw a top-down diagram to help...
