Molecules where the three ligands are not identical, such as H2CO, deviate from this idealized geometry. Examples: BF3, CO32-. Pyramidalization is a distortion of this molecular shape towards a tetrahedral molecular geometry. In chemistry, trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane.

Charles Ophardt, Professor Emeritus, Elmhurst College. The molecule all in a plane and is two dimensional. sp2. Since there is an atom at the end of each orbital, the shape of the molecule is also planar triangular. NOTES: This molecule is made up of 3 equally spaced sp 2 hybrid orbitals arranged at 120 o angles. NOTES: This molecule is made up of 3 equally spaced sp2 hybrid orbitals arranged at 120o angles. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. This molecule is electron deficient and does not follow the octet rule because it has only 6 valence electrons. Such species belong to the point group D3h.

Some ions with trigonal planar geometry include nitrate (NO−3), carbonate (CO2−3), and guanidinium (C(NH2)+3).

In an ideal trigonal planar species, all three ligands are identical and all bond angles are 120°. In organic chemistry, planar, three-connected carbon centers that are trigonal planar are often described as having sp2 hybridization.[2][3]. I Legal. Such species belong to the point group D3h. An example of trigonal planar electron pair geometry (E. P. G.) and molecular geometry is BH 3. The hydrogen atoms are as far apart as possible at 120 o.
