Example of molecule for square planar. point of the body is coincident with an equivalent point or the same point of the body in its original orientation). The point group symmetry elements are: Mirrors. C2v. Also, some ternary combinations of C … Cl2CH2 has two symmetry planes and one C2 axis. point group of TeCl4. All C 1 group objects are chiral. The mirror plane is perpendicular to the rotation axis, so this makes the point group C2h. Qty: ADD TO CART. 79 The order of the group is 6: 12 + 12 + 22 = 6 A fully worked out example: The derivation of the C 4v character table The symmetry operations in this point group are: E, C 4, C 2 4 = C 2, C 3 4, σ v, σ′ v, σ d, σ′ d.
