Which molecular geometry is least likely to occur with sp3 hybridization?

An sp3-hybridized atom has four electron domains, which arrange themselves tetrahedrally. Depending on how many domains are bonding pairs versus lone pairs, the molecular geometry can be tetrahedral, trigonal pyramidal, or bent. Trigonal planar geometry typically results from sp2 hybridization, so it is least likely with sp3 hybridization.
