  • 10. 3. 4: Tetrahedral Complexes - Chemistry LibreTexts
    To begin, it helps to know that a tetrahedral geometry is defined as having four atoms arranged at alternating corners of a cube around a central atom If we consider the orientation of the d orbitals, we find that they fall into two different groups
