# Can 2 dz2 orbitals form a π bond?

Usually , d orbitals overlap sideways along a common internuclear axis, but drawing and checking for dz2 , it always seems to form a sigma bond or null overlap. Is this because it doesn't have any nodal planes?

• Check out how the orbitals overlap when (1) youreversethe signs on one orbital and (2) you tilt each orbital by an angle of 35°16' making nodal cones of the two orbitals tangent to each other. The overlap seems a bit funky but looks a little like a $\pi$ bond, no? – Oscar Lanzi May 26 at 21:21
