In the crystal field model, ligands are treated as infinitesimally small (negative) point charges (represented by white spheres in the figures below). The orientation of each of the five unhybridized d orbitals in an octahedron is shown below. Note that only the total electron density is shown for each orbital, i.e., the phases for each orbital are not shown.
d_{xy}
xaxis = yellow Note that the electron density lies in between the point charges (i.e., the lobes of the orbital do not point directly at any of the point charges).


d_{xz}
xaxis = yellow Note that the electron density lies in between the point charges (i.e., the lobes of the orbital do not point directly at any of the point charges).
 
d_{yz}
xaxis = yellow Note that the electron density lies in between the point charges (i.e., the lobes of the orbital do not point directly at any of the point charges).
 
d_{x}2_{y}2
xaxis = yellow Note that the electron density lies directly in line with the point charges on the x and y axes (i.e., the lobes of the orbital point directly at the point charges).
 
d_{z}2
xaxis = yellow Note that the electron density lies directly in line with the point charges on the z axis (i.e., the lobes of the orbital point directly at the point charges).
