WebOne of the basic ways of applying MO concepts to coordination chemistry is in Ligand Field Theory. Ligand Field Theory looks at the effect of donor atoms on the energy of d orbitals in the metal complex. There are two ways in which we sometimes think about the effect of ligands on the d electrons on a metal.

Molecular Orbitals for an Octahedral Complex - Chemistry …
WebThis ion can take on two different electron configurations in an octahedral environment. With stronger donors, the d-d gap is potentially too large to promote a fourth electron into the next energy level, so the complex is left with two unpaired electrons.

11.1: Introduction to Crystal Field Theory (Octahdral complexes)
WebWe will focus on the application of CFT to octahedral complexes, which are by far the most common and the easiest to visualize. Other common structures, such as square planar complexes, can be treated as a distortion of the octahedral model.
WebIn chemistry, octahedral molecular geometry, also called square bipyramidal, [1] describes the shape of compounds with six atoms or groups of atoms or ligands symmetrically arranged around a central atom, defining the vertices of an octahedron. The octahedron has eight faces, hence the prefix octa.

Crystal Field Theory - Octahedral Complexes | Chemistry | JoVE
WebIn octahedral complexes, the lobes in two of the five d orbitals, the d x2−y2 and d z2 orbitals, point toward the ligands (Figure 1). These two orbitals are called the eg orbitals (the symbol refers to the symmetry of the orbitals).

WebKey Points. The term octahedral is used somewhat loosely by chemists, focusing on the geometry of the bonds to the central atom and not considering differences among the ligands themselves. When two or more ligands are coordinated to an octahedral metal center, the complex can exist as isomers.
WebIn an octahedral complex, the molecular orbitals created by coordination can be seen as resulting from the donation of two electrons by each of six σ-donor ligands to the d -orbitals on the metal.

WebIn chemistry, octahedral molecular geometry describes a molecular geometry in which 6 ligands are symmetrically arranged around a central atom in an octahedral geometry. All six ligands are chemically equivalent. The central atom is often a transition metal.
