Molecules with this geometry have infinite symmetry around one axis which leads to them having one more vibrational degree of freedom than a molecule without this geometry.
A coordination complex with this geometry would experience splitting that would stabilize the xy and x2-y2 ["x squared minus y squared"] orbitals and destabilize the z2 ["z squared"] orbital. Molecules with this geometry result in rotational spectra with equally spaced peaks since, like spherical tops, they only have one rotational constant. Molecules with this property are found in the (*) C∞v [C-sub-infinity-v] or D∞h [D-sub-infinity-h] point groups. Molecules with this geometry have infinite symmetry around one axis which leads to them having one more vibrational degree of freedom than a molecule without this geometry. The SP hybridization of acetylene leads it to having this geometry, which all diatomic molecules have. For 10 points name this geometry found around an atom whose two bonds are separated by 180 degrees.
