Deal with a variety of possible geometries and with a mixture of ligand. →Angular Overlap Model The strength of interaction between individual ligand orbitals and metal d orbitals based on the overlap between them. Molecular Orbital Theory - Octahedral, Tetrahedral or Square Planar Complexes The crystal field theory fails to explain many physical properties of the transition metal complexes because it does not consider the interaction between the metal and ligand orbitals. The molecular orbital theory

The extreme case of a tetragonal distortion is to form a true square planar complex in which the ligands along the z-axis are completely removed. In this case, the d z 2 orbital drops even lower in energy, and the molecule has the following orbital splitting diagram. A general d-orbital splitting diagram for square planar (D 4h) transition metal complexes can be derived from the general octahedral (O h) splitting diagram, in which the d z 2 and the d x 2 −y 2 orbitals are degenerate and higher in energy than the degenerate set of d xy, d xz and d yz orbitals. Answer (1 of 4): There are 5 d orbitals. dxy, dyz, dzx, dx2-y2 and dz2. They all have double dumbled shape. They are so named on the basis of their orientation with respect to X, Y and Z axis. 3 d orbitals are present between the axis: dxy, dyz, dzx 2 d orbitals are present on the axis: dx2-y2,... The next step is to start drawing an orbital diagram. The five d-orbitals should initially be on one level corresponding to the ionisation energy of nickel(II). The virtual 4s and 4p orbitals somewhat higher. The π-type ligand group orbital should be on a level corresponding to the ionisation energy of ammonia, the σ-type ones slightly below.

DISCLAIMER: LONG ANSWER! TENDENCIES OF #bb(d^8)# METALS #"Ni"^(2+)#, a #d^8# metal cation, is the metal center here, and #bb(d^8)# metals tend to make four-coordinate complexes like these, which are either tetrahedral or square planar. The difference in energy between these configurations tends to be small. Tetrahedral #d^8# tends to be high spin, while square planar #d^8# tends to be low-spin.

Apr 18, 2014 · Description. This in-class activity walks students through the preparation of a molecular-orbital diagram for methane in a square-planar environment. The students generate ligand-group orbitals (LGOs) for the set of 4 H (1s) orbitals and then interact these with carbon, ultimately finding that such a geometry is strongly disfavored because it does not maximize H/C bonding and leaves a lone pair on C.
