How do I Draw Tetrahedral Isomers?

Isomers are different compounds comprised of the same molecular formula. The different ways that the molecules of each isomer bonds together, constitutes varying isomers. A tetrahedral isomer is made up of an element with four connecting ions. Tetrahedral comes from the word tetrahedron, which means a triangular pyramid. Thus, when drawing a tetrahedral isomer, it will roughly represent a triangular pyramid. CuCl4 (2-), or tetrachlorocuprate (II) ion, is an example of a tetrahedral isomer.

Instructions

- 1
  Draw a small circle to represent the center of the structure. This will be the central element CU, or copper, for this example.
- 2
  Draw lines that will represent the connecting ions. At the top of the center circle draw a short straight line extending vertically from the center. Around the bottom half of the center circle, draw three lines of equal length and equal distance of each other. Position the lines as if they were to balance the structure if placed on a flat surface. The entire structure will look like a triangle.
- 3
  Draw small circles at the end of each drawn line. Label each circle with the sign for the connecting ions. For CuCl4 (2-), they each should have Cl for chloride label. The actual distance between the chloride ions will be 109.5 degrees.
